I noticed that the TE error checker quit catching GV spawns set to the same direction after I had completely populated my terrain with spawns.
I found them by accident after that which initiated one of my three rounds of visiting every single spawn on the terrain. On the other hand as a best practices issue, a minimum of three visits of every single base and GV spawn for an MA terrain is a good idea. I was amazed at all the issues I found with each round, and I thought I was being very thorough in how I laid down objects and painted around them. Kind of wished in the task groups tab was a tool that showed the map room objects so you could click on them and be taken to where you hid the derned things. At least I had the oba file.
