When you try to do the zero hour vault puzzle for the intrensic upgrades it doesn't progress. In the first area it allows you to shoot all 3 symbols but then nothing progresses. No text appears in the bottom left and in the vault room it says you haven't completed any of the 3 puzzles.

I just did this puzzle helping a friend out the other day. The prompt after shooting the symbols seems to not appear and/or show up way late but it did unlock the rooms at the end to finish the puzzle. Each shooting puzzle unlocks one room, so you have to do all three to unlock all three rooms to do the final puzzle for each intrinsic. They can be done one at a time too.
