I'll test this out later, just wondered if anybody else had issues.

So this happened to a single player, but not every player who opens their bank?

I added more null checks to InvalidateBank, let me know if this issue still persists.

thanks.
updated and re-enabled the plugin. i disabled it right away and didn't get around to testing it with other players. player lost some items and i had things to do. we were all using it last wipe no problem. 
i'll ask people to test it for me this afternoon.
