I seem to be stuck in a cave

I got a cave called Misty Cave which I seem to be stuck in. I managed to explore all that I can but it says I still have gems left to find.

I already looked under all the movable rocks, so that only area that looks like I can still explore is block off by this

Nothing in that picture responds to clicking. So anyone got any idea what to do now?

Keep looking :)

I have spent the last hour going all over the cave checking on stuff. No dice :/

Well I got some info/tip from someone so gonna try it it out and see if it helps.

Bleh nope just tried looking around the cave again with that new info. Still no luck :(

So it seems either the random generator for this map broke somewhere preventing me from proceeding or else I am completely missing some kind of door/switch somehow.

Is there some kind of debug option for caves which would reveal the entire map or something? As at this point I have no clue if there is anywhere left in the cave I can reach so it would help if I could see if there is actually anything left to reach somehow.

No debug "map reveal" option/shortcut for caves or quest locations, as that would also reveal secrets and Berserker would be sad :(

You have removed all obstacles in your cave ? Broken the medium slate ? Usually they block a path to a chest and lots of gems.

I believe the gem pile starts mentionning which gems are missing when you are missing only the last 5 or something.

The medium slate is in my 4th cave.

The one I'm stuck in right now is my 3rd cave I think.

Well 3rd cave I revealed on the map anyway. I think that's how it works.
