Had the same problem for 4-5 times already... I used the EA Support chat option and they told me they are investigating this issue... No answer or solution for us yet...
Yes it's happened to me 4 times. It's really annoying and frustrating. I keep gaining XP only to lose it and not be able to gain it back.
Same!!! Really frustrating, hope they can track this bug down, fix it and reimburse people. Idk how they would be able to tell what challenges were completed and then taken away though. They need to just gift everyone a couple thousand xp points.
Exactly the same here just got an objective and gained 700 xp. Went te get my rewards lvl 14 and got kicked out of fut. Went back and i was back at lvl 13 but the challenge is completed.
