I used the evolution tome to change into alpha form after I left the goblin camp and opened the gate to the bog as an Alpha. I posted the picture but it didn't take sorry. But when I opened the gate as an alpha it didn't register that I opened it on the quest menu, thankfully it didn't halt my progression but I did walk around a bit trying to figure out what to do, when I stumbled into the next step in the quest it updated and continued on so I didn't get soft locked and the quest shows completed, but that gate step actually still shows unfinished when I pull up the completed quest. Not that it matters now, but it did lead to some confusion on the next quest step for a bit.
