A boundary?? Like a map size limit? That can't be right because none of my maps are large, and this map was going to be a bigger one but this is literally the 3rd map I've ever made am still am ameture, so this is nothing compared to stuff like Dwell or Tremor...plz don't tell me I need to use the latest version of Trenchbroom so AI can make it work because I will give up entirely if that is the case. 

Sorry @metlsmile you are right, I tested it out with a new map and yes that is the limit. Blows my mind coming from Doom mapping because this limit is tiny compared to my basic Doom maps. It seem I can only run these bigger maps with Ironwail and QSS, which sucks that I am limited to that but whatever I guess, sorry for the confusion.
