I have paused work on Redo as there are some bugs with it in online and whatnot, plus floating bricks. It's not right for public release, but I could probably app with it if I fix one problem. Multi-Redo is very buggy.
For some reason, anyone but the host in online play gets their history set to 1.
I'll try to fix it, but it won't be perfect and I won't be publicly releasing it until the other issues are fixed that I don't feel like working on right now.
Oh and I'm trying to be as modest as possible.
Nevermind about the online limit thing, people meant that you could only redo one brick when you type the command once....
