I just had the same issue with my final ship battle. Went in with my best fleet and before the battle even started I got the “server maintenance” message. Upon restart, automatic lose.
This game is in dire need of a “start where you left off” or better yet, this sort of thing to NEVER happen.
Maybe I’m old fashioned but I prefer to lose over lack of skill or to be bettered by someone, not an rng simulator to say “are you going to win or lose today?! Nope you lost. Did you battle? No. But doesn’t matter! You lose! How fun”
Cmon CG you need to address this. At least compensate the people you’re affecting because this is ridiculous. EA support was a runaround to no where again when I tried that avenue.
