The server had BaseBuildPlus 2 and MMG storage mods installed, but I had not found or constructed any MMG items not BBP items other than some cement bags and concrete bags. Handling those items did NOT correlate to any of the issues I have filed bugs for, however I am unaware of whether a potentially problematic item from one of those mods was located nearby in Nadbor or not as my priority was getting away from the crash-prone area with loot intact.
This bug may or may not be related to other tickets I have filed, including T188653, T188873
