Sorry if this has been asked before So, yesterday I learned how to ghost merge, and when I was done, I saved my map. When I reloaded the map, I noticed my ghost-merged objects appeared to be back to "normal" standrds, that is, being unmerged and un geo-merged. Is this a common problem? No one was in my game.
Did you make sure to keep the teardrop hologram within the map? Make sure when you're geomerging to not merge that teardrop. If that doesn't fix it, then I don't know.
The teardrop can only not go under the floor of the Crypt. It can go outside of the dunes, the floor of the main level, and the walls/ceiling of the crypt... just not the floor of the crypt. I'd suggest flipping your objects over so the teardrop is on a face of the objects that isn't going to be merged into the floor of the crypt.
I'm guessing that the floor of the crypt is one of the inviolable "master" boundaries, right? (As opposed to a "normal" kill barrier or invisible wall.)
