Update downloaded and installed fine. Decided to drive into TT on CraterMA offline to take some pictures. Noticed that sounds still come and go randomly. For example the tank tread sound would be present. I'd stop and it would stop. Then I'd start up again and it would not come back. Resetv 3 didn't fix it. It's not just a binary thing either: sometimes the tank track sound is there, but very faint. Sometimes very loud. Sometimes gone. Same for foliage crushing sound.
Next one is confusing, sorry. I drove to the center of TT to take some pictures and noticed that the photogenic mountains circling it (the crater of CraterMA) were gone. I exited and went online to CraterMA and the mountains were back, but the very furtherest distant ones rendered either black or flickered in and out as I rotated my view. Sometimes they would render with black square patches.* I went back to CraterMA offline and the mountains were back. I went searching for a reason. One that I found: online CraterMA foghifarmiles is set to 25 and foglofarmiles is 12. Default offline is 18 and 6. When I go online the offline fog settings pick up the online for that terrain, despite the default and despite restarting the program.
