As there was a new fix released, I tried to get access to Frontline tonight as faction locked out of event since end October 2015. All members had deleted and reinstalled game previously, but nothing had worked.
Last week, we then left faction, started new one, bought all bonuses again, but lost concrete, and all our propaganda stuff for faction HQ, but thought as we were back in Frontline, it would be worth it.
Tried to declare war and yes success, message telling me and other members we were already declared and in a war.
Yeah, new faction, game still buggered. Oh well, at least it frees up weekends for things that actually matter.
