Turns out it was only an hour (picking start locations was 8min previous to the game start time due to the host booting for the first time), not 90min, but it sure felt like it!

Even if it is essentially just abusive settings, I've noticed boot bank timers refilling with other players too and it really annoys me. If you're playing 4 games at once very slowly, getting booted and it's ruining those games for the other people, why not just play multi-day games instead? To me, a 3min turn is a 3min turn, and banked time on small or medium-sized maps is just a grace period in case your computer crashes or you lose connection.
