Well to be fair I am part of the realms sorting it out, but I wanted to know how the devs feel about it (whether the devs answer or if anyone else knows anything) so we could know what we wanted to do.
Unless the effect of a bug has some major, game-breaking effects, then the dev team will not interfere in IG events beyond fixing the bug itself. As Anaris says, the regions will not be transferred back to the original realms. Yes, it sucks that Sandalak was able to take Toren Stronghold in about 10.5 hours. But Sandalak also lost Korlok to the Ikalaks in a TO that went from 44% to complete in a single turn.
It's a bug. We play through it.
We haven't agreed if there should be a ceasefire, a turnover of the region or business as usual yet because I think we wanted to confirm it was a bug.
IMNSHO: Play through it. Stop with all the agreements and cease-fires and deals, and attempts to "make it fair". Just play.
