Update: I tried activating and deactivating all the profession one by one and see if I could find which one was the problem.
Apparently the problem was the fisherman profession, I had 2 fisherman’s in the river and when eliminating those I managed to go pass the crash point. I´m still sending you the save game around 20 sec before crash point.
On Steam is 7.1.2 with the forester bug fixed. So it’s not that.
I checked your trout fishers and it seems like a conflict between the bridge and the spot that is close to it. It doesn’t crash if I remove this close fishing spot or the bridge. The other spot is not a problem. A conflict might be caused by placing trout baskets left and right of the spot. It should be just placed on the bridge then and the fisher is actually not working in the moment it crashes but who knows. Maybe something fails because the bridge was finished right before. Anyway, I can only guess and try to avoid such by changing the fishing spot in a way it doesn’t occupy adjacent tiles.
Thank you for reporting and narrowing down the problem!
