Randomly cannot use attacks but can move

Hello,

This issue *seems* random. Fairly often, at least a few times every map, all of character's attacks stop working. Have mana, no status effects, nothing greyed out, can move, otherwise doesn't seem like the game is lagging. Just attacks completely unresponsive. Often nothing nearby attacking me.

It seems to last about three or four seconds then clears up on its own.

Things I've tried so far:

making sure "sticky keys" is disabled in Windows
refreshing mouse stacks
switching attack in place keybind from shift to spacebar
praying
google

This happened to me exactly once and then I never saw it again. It was right after dying to the Act I boss. For the first 10-20 seconds of my next attempt, I could move around, dodge, etc, but I could not do any attacks. Then, it magically started working again.

I've had it happen as well, almost always when I hit buttons in the middle of a fancy animation. The easiest is when getting off the elevator into the last boss of act 1, but other long transitions can do it, too.

I've noticed this a lot (maybe once every three maps) as well. Not sure what causes it, but it happens more when I'm clicking more frantically and/or use dodge, so I wonder if it's related to attacks going into a queue and needing time to clear.

EDIT: Looks like the most consistent way to trigger this bug for me is to be spam clicking Ice Strike a rare monster and then dodge rolling immediately once the monster is dead.

This is still happening.

I'm probably going to have to give up the game soon. Being surrounded and not being able to attack in endgame, which is pretty common now, then losing entire map is a pretty big deal.
