[b]EDIT 15.AUG: PROBLEM STILL PERSISTS. Sorry this is a nasty bug. Will do more testing over the next few days.[/b]
Today I updated the servers with a new version of Immune to fix the bug, that caused items to disappear from your loot boxes after server restarts.
Please let me know if you still experience disappearing items (please make sure no one looted them).
Have fun playing!
