Hey there.

If your online match desyncs, please do me a favor and tell me:

• What characters were used
• What stage was used
• If you played multiple matches in one lobby or if someone quit your lobby and someone else joined or anything weird like that
• If items were on or hazards were on
• Anything else notable you think we should know

PLEASE DO NOT DISCUSS HERE, WE NEED TO READ THROUGH A LOT OF THESE AND FIND/FIX THE ISSUES!

What characters were used: Falco (me) vs Peach
What stage was used: Final Destination
If you played multiple matches in one lobby or if someone quit your lobby and someone else joined or anything weird like that: After accepting the Peach I had like 4 match request that I denied while on the CSS.
If items were on or hazards were on: None
Anything else notable you think we should know: Nothing comes to mind.

What characters were used: Several as this has happen a couple of times.
What stage was used: Same answer.
If you played multiple matches in one lobby or if someone quit your lobby and someone else joined or anything weird like that: This has happened when it's the first match of after logging out.
If items were on or hazards were on: None
Anything else notable you think we should know: After accepting my opponent in the room and a successfully locked message appears, I still get a chain of request from 3-4 more players. I deny them all and the match with the first request opponent starts, but freezes the first few frames of the match... I'm taking a guess as it doesn't prevent the start of the match everytime, but I'm seeing a pattern of when that chain of after-room-locked requests happens, the match tends to freeze at the start.

EDIT: I'm positive now that chain of request freezes the match. Happens everytime.

What characters were used: Peach (me) and MK
What stage was used: Waiting room
If you played multiple matches in one lobby or if someone quit your lobby and someone else joined or anything weird like that: played 1 match, then the second one started to desynch.
If items were on or hazards were on: None
Anything else notable you think we should know: I have a replay of it if it's needed (Also when loading a replay, at the moment where the no contest screen appears, it shows the host of the room winning instead of no contest)

What characters were used: Bandana Dee often and Falco a few times.
What stage was used: Battlefield
If you played multiple matches in one lobby or if someone quit your lobby and someone else joined or anything weird like that: It often happens after a consecutive number of requests, the game freezes afterwards.
If items were on or hazards were on: Only hazards as I didn't intend to disable them at that moment.
Anything else notable you think we should know: People still point out that moving in the waiting room causes the freezing. And honestly, after actually not moving in the waiting room, it didn't freeze. I don't remember a game where it froze after not moving in the waiting room and vice versa.

I just came across a glitch where I joined a match that said 1v1, but 2 people connected. I guess the host accidentally accepted both of us. The first guy (not the host) disconnected, then I selected Bandana dee, and waited in the waiting room for about a minute and a half. The host disconnected, bringing me back to the selection screen. I was practicing combos, so I accidentally pressed spacebar as soon as that screen came up, and now I'm in the waiting room with no way to get out.

And now I just joined a room where it was going to be a 1v1, but then I spontaneously disconnected.

Then I created a match, also 1v1, accepted 1 player, no other player tried to connect, but then when I clicked the "Click Here" text, the screen just went black.

Am I saying too much? Sorry about that.

What characters were used Both used B-Dee
What stage was used Dreamland
If you played multiple matches in one lobby or if someone quit your lobby and someone else joined or anything weird like that 1st match 1st lobby
If items were on or hazards were on Could be coincidence, but it desynced pretty much right after the hazard began. no items

Nah, I get desyncs even if I stand still. And i get desyncs even if I only get 1 request. It's something else for sure.

Ichigo and Isaac

No items or hazard
2nd lobby and first match with that individual
1 request after I accepted him

MK and Bdee, battlefield
No hazards or items
2nd lobby 1st match

What characters were used: Falco and Naruto
What stage was used: Final D
If you played multiple matches in one lobby or if someone quit your lobby and someone else joined or anything weird like that: First game in that lobby
If items were on or hazards were on: None I think
Anything else notable you think we should know: Nope

There's one thing I noticed.
It seems everytime I get a desync, the alternate music is playing. Can anyone confirm this?

What characters were used: I was Sandbag, my opponent was Bandana Dee
What stage was used: Final Destination
If you played multiple matches in one lobby or if someone quit your lobby and someone else joined or anything weird like that: nope, only match in the lobby
If items were on or hazards were on: nope
Anything else notable you think we should know: I'm not sure if this was a desync or a legitimate mistake on my opponent's part, but they SD'd for their first two stocks and disconnected after so I'm pretty sure it was a desync. I have a replay, but I doubt it saved the match properly. I can confirm, the replay saved what I saw. The only incorrect thing is the ending; it ended with a 'no contest' screen, not a Sandbag victory pose. I do like the wink, though.https://drive.google.com/open?id=0B0oWmApLgI_ecS1YamRrMWpvZTQ

What characters were used: Marth v.s Meta Knight
What stage was used: 3DS Stage
If you played multiple matches in one lobby or if someone quit your lobby and someone else joined or anything weird like that: Don't know what you mean, but the desync would always happen on my first match online every time I opened up the game.
If items were on or hazards were on: Items and hazards were both on.
Anything else notable you think we should know: Nothing in particular.
