I noticed that when I left click, it destroys more than one bit. I usually use Draw Region mode, but I've noticed that even Single Bit mode is effected by this problem. Basically, I left click to break one bit, and even if I quickly release the mouse button, it still does more than one destroy action.

Here's a video of me in my server trying to modify a sign with this bug in action (unmute to hear my mouse click):

For reference: The server is running on another machine on my local network.

Hrm... The Draw Region Mode might be less bugged in this version... Oh, nevermind... It happened on this mode too.

Having the same issue, but noticed when using the chisel tool it works correctly for me. it only happens when I subtract pieces with holding bits in my hand

Really? If that's so, I guess I'll have to carry a chisel when modifying signs and features in the meantime. Though, this does mean I'd be wearing out a chisel when I shouldn't have to.
