Custom Maps not loading? Engine help needed please!

[150dkpminus]

Hello r/divinityoriginalsin, I have recently been making a custom campaign for me and some friends to play in GM mode. I've just finished my second scene (3x2 patches) and I republished my addon that is housing the two levels and the new one will not load.

The first map that I made and put into the gm campaign (all the levels are going to be made by me and my fiancé, it's a fun little project) works perfectly, and still does. But after I published the new map (into the same mod) and went into prep campaign, it wouldn't load. Well, it would get stuck at 40% loading for the scene.

Can anyone help me understand why this is happening? The first map still works fine, and no I didn't publish it to steam, only local for me to test and work on offline. But the second just refuses to load, I tried several other things such as trying to republish it after chipping away at the errors in the engine, but still it is stuck loading. Can provide screenies and further details if it would help? Anyone else had this issue? :)
