Pop files not loading on custom MVM map.

[dillwax]

Hello, seasoned mapper here. I've decided to finally try making an MVM map and have done everything needed. The whole checklist is ticked. However, when I go to load a .pop file on my map it doesn't load. No errors show up or anything either, quite strange. I've successfully loaded pop files on other maps, including custom ones, but for some reason it doesn't work on mine so I've got to be missing something. I've tried researching a fix but almost no relevant results came up so any help is appreciated!
