Glad to hear it's resolved.
After upgrading to 0.4.1 when I try to remove users it takes longer and it doesn't fade out the user box. On top of that, when removing like say 5 in a row it crashes my board.
Does it restart the forum when removing a user?
Thanks for reporting should be fixed in https://github.com/designcreateplay/NodeBB/commit/fdfd421e1c89a395e4385fc318d3556dd408d729
