OK so I was playing both sides (BOS and the institute) I took on x6-88 as my companion and when the mission "mass fusion" came up on both sides I couldn't do anything with the institute so I went to the BOS to complete the mission with them it made me an enemy of the institute and x6-88 is now fighting the BOS and won't die or leave I've gone and done other things hoping it would correct it self but with no luck:/ any help would be greatly appreciated
