Conan exiles and external hard drive?

Hello today tried to move the game on the Xbox oneX on my external hard drive unfortunately I had to realize that although you DLCs verscgoben were the main game but for some reason not moved to the external disk have the game already deinstaliert to esziehlt on the instalieren external disk have the instalationsort on the settings changed but the result was similar to the DLCs were downloaded and instaliert the main game but was not downloaded.

Is there any known that the developers do not support external disks or something?

It may be that they do not do that for copy protection.

Okay, that's a little stupid I've never had this at a xbox game
