Before the crash earlier in the day we received console spamming of this error "Found null entries in the RF listener list for frequency 55... cleaning up." Happens for a few minutes and dies off and repeat again later for the same amount of time. It's happening as I speak around 11pm. I can subdue the console spam but doesn't solve the route issue.
Found a solution that might work but I don't have access to necessary library. Umod has some success in getting rid of it with this solution.
"check in better loot config/data take it out see if resolves the issue i think better loot spawns the item but it may be spawning the item entity. or somthing may have changed with the item in rust."
Hope this helps!
