[1.5] Error when loading a mid game save

[coloso22]

When I load a fairly advanced (mid-game) save, it crashes seemingly randomly. What happens is that the left-hand item menu no longer appears, I can't select anything (not even warehouses or colonists), and all the storage areas disappear. I play with quite a few mods (approx 173). I've tried removing them all and the save doesn't fix itself, it just shows a gray screen with the character names. This has only been happening to me since I got Rimworld version 1.5. I've attached the log it gives me. Can anyone help me?

Example of the error:

Exception spawning loaded thing Wall200827: System.NullReferenceException: Object reference not set to an instance of an object
[Ref 433AAB4E] Duplicate stacktrace, see ref for original

Unfortunately, there isn't much traffic on the forums at the moment, the recently purged spambot flood kept everyone away. I'd suggest either joining us on Discord -

Community server for troubleshooting both modded and unmodded: https://discord.com/invite/UTaMDWc

Or pop over and post on the Subreddit at https://www.reddit.com/r/RimWorld/

At the moment, those are far more active, and hopefully we'll be able to help you better there!
