World Builder Crashes With Mods?

[Magma Mambo]

Hi there I am a new CIV 6 super-fan and I've recently discovered both Mods and the World Builder Feature. I spent several hours creating a fun map for myself and the mods all worked fine (including mods to bring in new Natural Wonders/Resources), but after stepping away from CIV for a day I came back to try to edit the map (having the exact same mods still active) and it crashed saying that the mods failed to load. What was interesting though is that I tried playing the map and sometimes it would work and sometimes it wouldn't....it seems I can't go back in and edit it though??? Anyone have any tips to help me with this dilemma! I tried doing the "TZ Method" but it ain't doing nada. I love the mods but would prefer not to turn them off to create the maps I'm envisioning.
