Update:
The known error: "Object reference not set to an instance of an object" appeared again but only once in about 10 raids.
Maybe someone with a bit technical knowledge could have a look at the attached error log.
So i had the error and may have a possible solution:
I had the same issue with my save and the following mods active:
- BandanaOfProtection
- ClearVision
- ServerValueModifier
After some trial and error i found that the issue could be related to increasing the size of containers above the values of standard and then using the extra space for items.
So i increased the size of a lucky scav box from 14x14 to 15x15 and filled it up. As soon as it was filled the system threw the error after every raid. I then emptied the box and the error disappeared.
I changed the size back to standard 14x14 and filled it up again and the error did not appear again. I will monitor everything for a while but it really looks like its related to the change of container size.
What i also found is that the issue could be related to weapons that are folded and the space they take changes. So unfold you weapons.
