while playing in my park (which is not hitting object limits) my game randomly froze after placing down base game scenery.
after trying to reopen my save it will now freeze after around 5 seconds. pausing the game and closing all the rides does not help so i dont think it has something to do with the coasters in the map.

Reproducible in ORCT2

Steps to reproduce:

1. load up the park
2. wait ~5 seconds
3. watch it freeze

Save game:
