T1 Def Mission Failed When Host (After Migration) Claimed Reward And I Stayed

[(PSN)fiendnix]

4 players in t1 def. Player A was host and it host migrated to Player B. Wave 5 reward was t1 cap key and all 4 players stayed. Wave 10 reward was t2 md key. Player A and I stayed and the other 2 players claimed reward. When the timer was up it says "mission failed" for both me and Player A

Encountered the same bug while playing t4 def. 3 players were in the game. Player A is the original host. Host migrated to Player B before game started. At wave 20 ember p bp is the reward. Player B claimed reward. Player A and I stayed. Host migration happened and it showed mission failed for me. Player A ended up in game alone
