Cant load up server or client, even moving the player mixin to clientside stops the server from crashing but now i cant launch my client.

debug.log
latest.log

That's a simple incompatibility with another mod patching EntityPlayer::onUpdate in the exact same spot as Aqua Acrobatics does. Does this version work better for you?
Also can you please send another log without Aqua Acrobatics? Just the normal one (latest.log).

Sorry, wrong button.

The build u sent works perfectly fine.

latest.log

Awesome, thanks!
