Summary: 0011696: Fedhas' mushrooms freeze when they see monsters in ghosts vaults
Description: Rather annoying now that ghost vaults are more present. Even though the monsters are safely trapped behind runed doors, your mushrooms won't move at all if they see one. Can require a lot of manual repositioning if the ghost doesn't appear in LOS until you're close.

Yes, also autoexplore stops even though monsters can't get to you, often. I feel it's relevant.

Hmm I can't replicate what you describe; Fedhas' mushrooms seem to work fine when there are ghosts behind glass for me.

Mushrooms freeze in sight of monsters behind glass because there is a possible path to you that lies through unknown squares. Once player's known map shows that monsters behind glass can't get to you (even through unknown squares) mushrooms will move normally.
I don't think this is something that should be fixed.

Edit. Well, maybe introducing a cap for a minimum length of possible path would work.

It turns out the issue here is that if you are introduced to monsters behind glass where you haven't seen them fully enclosed, and then subsequently find them fully enclosed, sometimes the mushrooms don't get unfrozen and so you have to manually free them from los of the monsters behind glass.

Here's a save where I'm in a gauntlet and my mushroom is completely unable to move on its own.

sharkfinsouperman experienced a bug with Yred where his allies were determined to go after monsters behind a glass wall. I assume it's another manifestation of the same problem. See uploaded sharkbug.png
