Slab becomes impossible to cross

[Loobinex]

To reproduce: 1) Load this map: map00004.zip 2) Make some imps and have them dig straight west from the heart -> Notice imps will not claim beyond this spot: 3) Make a treasure room and drop the imps west of this slab and notice they will not be able to make their way back.

I did some investigation:

• Creatures who can fly or lava walk can pass the slab
• It's slab (15 , 55) that is blocking
• Slab (15 , 53) is lava, if that is not lava, they can freely pass the slab
• making the lava river smaller in a map editor also prevents this issue, see screenshot:

I get several reports of this bug in different forms, of pathfinding seemingly broken through open ground:

My Imps can get to the door and back just fine 😕.

What do you do? Just load the map, tag left, build imps and frameskip. You should see the claiming stop partway.

That's just what I did (sans the frameskip). They hesitated, but claimed all the path, and reached the door.

This is not just for me, it was reported by a user and look at with others too.

This is what happened when I tried it:

Already weird, but at least you can also reproduce them stopping the claiming past that point. If you reproduce from the start and build the treasure room like I did, can you also get the message that imps cannot get there?

Yes, but here's the rum thing: I get the bug, but saving the game and reloading the savegame fixes it 😕.

In the older days the pathfinding bus also reset itself after loading. Something about navigation is cleared on each save/load, possibly the navigation colors.
