I used the editor to increase my transfer budget to by Jovetic for Sevilla from Inter Milan. He is now in both teams. I can't use him for the Sevilla games because he is ineligible having already playd for Inter on the same day. In the editor he is also on both team rosters but in the Inter roster it indicates that he is at Sevilla. Is there a way to fix this? Thanks
The issue you're describing doesn't seem related to FMSE. I mean you've used the editor to increase your budget, not to change the player's club (not possible yet to do with FMSE).
Out of curiosity, did you continue to the next day or are you still on that same day he played for Inter?
