woops ...it's fixed. I didn't noticed my last update was broken and I was gone to see my family. Bad timing, sorry about that. Merry Christmas to all of you!
It is a race. If your opponent captures the flag first, both flags reset. Strategy: wait for opponent to complete capture first (if he is already closer than you are) - then go for it! ;) Also, encourage your teammates to escort you, and to slow down or destroy the enemy carrier.
just go along with the enemies hp and dmg and you wont have any problem! also place your 1st tower as close as possible to start point so you can one-shot kill!!
fixed, thanks for reporting the bug
