You can export them from the load menu.
But i'm not sure if that's what your asking for. So can you explain the question?
Id like to take my current save/character and move them to the new apk- like you said to export it and all
Then yes. You can export the save and it will be outside of the app when you change over.
You can import the save in the load game menu.
I did this and ended up restsrting actually but now i have an issue of people not appearing, I dont know if its due to mods or not though-
Oh are you talking about character's with parts from mods missing parts? If so the mod author's are trying to fix them.
