There still will be. Fixing a bug always creates new bugs. There’s no such thing as a perfect product. As long as flowlab is a beta, there will be bugs.
Behavior dragging and connecting don’t work for me. When I click on the behavior and want to drag it, it will just stay there and won’t move. Same with connecting the behaviors. When I loaded an older game though, it worked without any problem. So I think it doesn’t work because of this update.
