I don't have a problem, this is just a question.
I've set a mark/recall in my Skingrad house. And I frequently go back to dump loot and then fast travel right from the house and into morrowind map. Since opening the world map brings out the morrowind worldspace - it's not a problem. I've been doing it for 20-30 hours of gameplay now. But I recalled that I read somewhere you can cause problems with that.
Is this safe to do? I don't want to lose my save as it's a 100% oblivion completion and I'm trying to do the 100%-ish morroblivion in the same save
