Yes, these triangle signs appeared ca. year ago. When I try to go to the corrupted lots, the game fails with an error. But this has not been such a serious problem, so I have continued in my game and just avoid these lots.
So there is no way to fix it at all? Of course, I thoroughly searched for solution of the exlamation points bug as soon as it appeared - without success. As I see, the solution still has not been found. Corrupted lots are not a problem for me, but whole unaccessible world makes impossible to finish some aspirations, which is really disappointing for me.
It is just so frustrating if I should give up of almost 10 years of playing with a very complex family and of my buildings...☹️
