I updated today to the latest versions of the plugins etc. and something must have gone wrong because at least one building got completely messed up etc.
I realized this some 2-3 hours after updating the server. So instead of trying to fix something that is almost impossible I rather opted to revert the map to the status it was when I updated. This means that if you logged in right after I updated, all what you did until this blog post is undone.
Sorry about this, but but could not help it.
