Cannot advance on final stage.
At the final stage, right before reaching Methuselah, I can no longer use the elevator since it is stuck at the top and cannot use the mid-range zap pad to Methuselah for some unknown reason. I know it was activated since I backtracked to the beginning to search for upgrades. Does this have a solution or do I have to restart the game yet again?
This is fixed in the next update.
In the meantime, you can fly up and enter a gap on the right side of the elevator to get above it, then lower the elevator down to grab the shepherd body.
We will fix the mid range zap issue in the next update as well.
