MoAppCrash anyway to fix?

I keep getting MoAppcrash errors when the sim crashes to the desktop. It happens in specific scenic areas. At first, I noticed it happening at just a couple of places. But today it has expanded to another area that I have had no problems with.
I’ve read a little about it but haven’t found any way to fix the problem. Any help directing me to someplace I can go to and fix this problem would be greatly appreciated.
Thanks very much
