Re: Geth in the Tunnels on Feros Bug has existed since 2008
I cannot say the bug doesnt exist or that Bioware aren't a bunch of incompetents.
However, the Geth in the Tunnels assignment isn't part of the main quest. None of the geth in the tunnels/water/varren meat/power cell assignments are part of the main quest. You can safely take the elevator up to the skyway and proceed to exogeni hq without helping zhu's hope. It sucks to not help them but you aren't stuck on it, which is probably Bioware's reasoning for not fixing it.
