I have seen a number of comments lately about the map not loading or even crashing. I have never experienced such a problem, which is good for me but unfortunate for you because I can’t tell you how to solve the problem.
If you want to solve loading/crashing issues, I would recommend two items:
(1) the folder %localappdata%\Teardown contains a log file of the current session. Any errors should be logged there so it may point you to the root cause. There’s also crash reports in this folder but don’t ask me how to interpret those.
(2) I still suspect interactions with other mods. So you could try deactivating those mods and see if that solves your problem. You may also give me a list of the mods you‘re using and I will do the testing.
