Not really a bug but still an issue of sorts, basically as there is no warning as to when the server will be restarting it is impossible to know what will be saved or lost upon a restart. This means that on a few occasions I have either lost some decent loot or even been killed as a result of there being no warning as to when the restart will occur. I don't think it is just the fact that it restarts without warning that is an issue, more the fact that player progress sent to the main database is behind the server by about 5 mins or so, meaning that anything done 5 mins before a restart isn't saved. A simple 5 minute warning or something along those lines that most of the servers for the mod seemed to feature would fix this problem.
