i would expect so, but that is a more specific question. It may be worth making a new thread if you can’t troubleshoot it yourself.
Might test to see if it’s just specific to the map itself, or the uobject. I.e. if you try to save/load a map in some actor, does it work? If so, then there must be something about using the uobject, otherwise it’s just something about saving/loading maps.
It’s not something i’ve dealt with before so that’s the most I can offer unfortunately.
