I was wondering if 5.5 is still buggy
yah its not bad i think its less buggy then 5.4, I did not get chance answer your question on the server.
Its server does not even crash or hasnt so far.
other then having to be reloaded form backup due to people using there land markers to close off other peoples properties
There is a mod the server owner can download and use to remove deeds claimed by other people, instead of using a back up every time it happens.
