I was on elevator in bunker and put in a pattern on a puzzle and I guess it was wrong...I saw two colors of blue dots and I guess I should have included all blue colors in the group.
If you enter any other pattern then I think the elevator will go back down to a previous floor, so you can get out and try other places on the island.

I know the post that I'm replying to is from 4 years ago, but as there's only 7 threads in this game's forum it seemed fair to reply to one that sounds like a game-killing bug.
The elevator goes downwards, if you enter any invalid combination. To go up a level, you need to group the current same / compatible color fields
