No Dice. The thing weighs 600kg. Even Karlach and Lae'Zel, both with 19 strength and used enlarge on, only get 288 capacity.
Edit: But I can 100% confirm that's the issue. I loaded an autosave just before killing the Lava Elemental, and from there I can travel between Act 1 and 2 no problem. Means I have to rekill the Goblin Leaders and do the entire Mountain Pass again... oh well.
If you're on PC, install one of the carry capacity mods like "Carry Weight Increased - Up To Over 9000".
Alternatively, reload an earlier save from before the fight (if you still have one).
I'm hopeful they'll fix this in the next week or two, though.
