Hi again,
I migrated all the assets to a new project but eventually the error came up again. After messing around with the engine, I found that I had another map using the same assets/textures so i deleted it (just in case) and it seems that it worked… Now im able to build everything again and no error.
Every time I open the editor I in this phantom level (which has nothing on it) so i move to my custom level and decide not to save that old one. Is there any way of seeing ALL the levels/maps inside the same project, so that i can delete the unwanted ones?
Regards,
Seichi
