Do you have tap jump on?

I did but not sure if it's normal for that to happen.

i think its because to do an up smash, you press the up key, which for you is mapped to jump, causing him to, in a way, jump right before the up smash, therefore playing the sound.

I found 2 glitches:

If Black Mage uses his Down Special while in the air just a frame before hitting the ground, a growing Meteor will go flying up, like in the occasion where another character hit Black Mage during Meteor. I haven't got a replay for that one.

I am not sure I mentioned this one yet, but it's still on the last version, so I'll mention it anyway. If you pick an Assist Trophy and just hold left/right when you hit the ground, you'll not activate the Assist Trophy. So far it looks fine, but while you're in one of your 'strolls', if you press the primary attack button while still holding left/right, you'll summon the Assist Trophy while still holding it. You can pretty much spam it that way, and the limit of how many Assist Trophies can appear on screen (normally only 1) will be increased to how many times you summoned the Assist Trophy. Here's a replay showing it:

Both of this is known, the Assist Trophy Glitch has been reported by literally everyone on this forum now.

@Mods Can you PLEASE add "Read OP First!" to the thread title?

I have downloaded SSF2 at least 5 times and it still will not load. I have downloaded it from the official download link from mcleodinggaming and will not load. I is stuck on the loading screen and it has a blank in front of the percentage sign. Does anyone know the solution to this?

me and my friend found a bug in multiplayer i keep dying in my friends screen and he dies on my screen plz fix

Thats a desynch, which means that something disturbed your connection. Will most likely be fixed in Beta. Not moving in Waiting Room and resetting the game after each match usually helps getting around this however.

I am afraid I didn't get a recording of this, but I will try in the future.

On several occasions, I've had double trophy assist characters spawn from a single item if I repeatedly hit the attack button while holding one. This first occured on the bounty hunting event, when the AI Goku picked up a Renji trophy.

I'll get back to you on the footage.

There's literally a post about this in this page and Skailler already replied that many already know/have found this bug.

Furthermore, Goku doesn't appear in Bounty Hunting.

I made sure I read the OP (as well as the linked thread in it) this time, and there's no mention of an assist trophy glitch on either, except for one where it has been 'fixed'.

With that aside, I found another glitch on Peach's Castle where, if anyone is hit into those ! blocks with enough knockback before they are 'activated' (and only on the bottom part of it), they'll stay locked there until they're attacked out of it, or until they get out of it if the move used to launch them there wasn't going straight up. Attacks that come before the actual characters also seem to activate this glitch. I tried to do this a few times and one time both characters (there were only two in the match) hit it at the same time, causing the game to get stuck there, though I was able to quit it. I may be wrong, but it doesn't seem to happen in Training Mode.

I will probably report many glitches so I will instead upload the replay in my Dropbox. Here it is.

And your first paragraph is why Im begging that the OP gets updated for the last pages. The other one is new tho (or I just missed it).

Omg guys stop reporting about the assist trophy glitch....

There's a glitch where on Yoshi's Island, as Yoshi, you can do Yoshi's Down-Special on one of the edges of the stage, where it slants down, and get stuck in the animation on the platform above you. You can move around freely until you come down from the edge, where the animation continues. You can also hurt enemies.

Can't picture too big, but you get the idea
