So, I've been making a map for a minute here and it's been going fine. Meshes work, no crashing, etc. But, when I log into the game and decide to go check out the map for myself, I notice that every den I'd placed (All from the same 'Group') didn't show up. I went back into Map-maker, back into the map, and everything worked fine. Logged back into the game and BAM. No dens.
I really put a lot of time into the map, and I don't want to have to start over. Could anyone please tell me how to fix this? The meshes are from WarriorMeshesII, if you were curious.
Thank you!
How the issue was fixed:
I made a flat map and placed all the broken meshes into it, exported it, and closed out my game & reloaded it.
