Game breaking bug when visitors arrive

[Sempius]

Hi! I'm having a very weird bug where I can't seem to click on anything a while after visitors arrive; also, the interface dissapears when I zoom out, and reappears, sometimes, when I zoom in. Rolling back a save seems to fix the problem, but it happens so often it's quickly becoming unplayable.

On the surface, what I notice is that one or two visitors just dissapear, and looking at the logs it looks like it's trying to draw them but can't find where they are (or where to draw them).

Now bear in mind two things: first, I don't know if this is normal, but my output log is very big (25mb for a .txt seems like a lot); second, I play with a shit ton of mods. I hope this is not a deal-breaker for trying to get help on the forums because I really can't think of anywhere else. Anyways, I will provide a mod list if needed.
For now I'm just giving you my output log because I can't recognize, just by looking at it, whether it's a mod causing it or a conflict between different mods (given the amount, I might have missed one compatibility issue or load order instruction)
Let me know if I missed any information you might need.

Please, help me; and thanks in advance!
