Pekka missing from Clan Castle Attack during war

I have donated my clan mates two lvl 5 pekkas to their clan castle to use for war attacks. But during the war attacks when they dropped their clan castle the pekkas were no longer there. instead either nothing or whatever else was in the CC was deployed. However, after they got back to their village (after the attack) the lvl 5 pekkas was sitting inside their clan castle just waiting. I think this might be a bug in the game and was wondering if you could look into it and let me know.

Thanks Clash team and super cell

We experienced that also. During war. My my 1st clanmate ask for level6balloons. Her request disappeared from the chatbox. After few mins she requested again coz shes ready to attack. Then leader told her. " Ive given you balloons already, it must be stuck in traffic". Leader just gave another set of balloons. Then she attacked. After roughly 30mins. Shes posted " leader you 2nd sets of baloons arrived". During the same war, 2nd clanmate ask for dragon. Same thing happened. Request disappear from chatbox. Leader had given him another drag. He attacked. Minutes later 2nd dragon arrived.
Lesson here, check cc before attacking.
