Describe the Issue

While being on a server, once i open the inventory it crashes, i looked at the crash report and it seems that is specifically related to how LevelZ handles player stats and tooltips when opening the inventory. Does someone know how to fix this, or if theres a similar issue that has already been fixed plz tell me. Thanks
