I've attached the crash log and the most recent autosave. I've also attached a picture showing approximately where I was standing when the crash happened. I wasn't able to reproduce it by going back doing doing the same thing, though.
I hope this helps, and thanks for making such a great game

Edit: I have many mods installed, but not active on this save. I also just got another crash on the same save, in a different location, while placing down a large power pole -- I've attached its log as well.
I updated to 0.18.36 last night and then played for a few hours and experienced nothing like this.
Edit2: Oh no, a third crash. I was holding a roboport, about to place it. I've attached its log file as well.
