I have been playing on a modded multiplayer server running darkness falls. The issue is that after playing for several hours I will get a null reference error pop up in the console and I will no longer be able to interact with any inventories. The only fix is to relog. Upon relogging, I will find that I have reverted character progress to a state several hours earlier. I will also relog in a completely different position on the map. The server's data is unaffected as I will have the same inventory as when I logged off and any vehicles and or drones will be where I was when I logged off, but my Perks and Levels will be reverted. After this happens my save file appears to be permanently corrupted. From this point forward progress will not save when I log off, this remains true whether I play for 5 minutes or multiple hours. The first time this happened after playing for several days on the server. I completely reinstalled the game, mod, and mod launcher. I made a new character and the issue happened again within a few hours. I have my output_log file but the upload file button will only allow images to be uploaded.
