No idea why that would happen, maybe contact support about this issue and see what they can do for you.

Hello, my Lord! 

The thing is you attacked the Fortress and received the flag, you won't have a chance to attack this Fortress during 2 hours. Other Leagues won't have a chance to attack the same Fortress during 1 hour. Thus, you can meet some differences in time for the attack. 

That isn’t correct Alina.  That fortress lost its flag the day before to a completely different league, neither of the ones from the screen shot. So, why then are there different timers?  I’m still confused.

P.S. We did contact support and they said bring it to the community forum, which is completely strange, so here we are trying to get a better understanding of what happened.

As far as I can see on the screenshots, the first screenshot Fortress has cooldown 1 hour and 13 minutes, and another one - 13 minutes. I guess it happened because timer for League which attacked and other Leagues can be different. 

If I understood wrong, please give more details when the Fortress was attacked.
