Bug: Grolden Chambers: A block stops being recognised as block

[wisprabbit]

Reported by Muftwin. In Muftwin's playthrough of Grolden Chambers, an A block became inactive, and was treated as a step rather than a pushable block.

Unfortunately, it's not known how to reproduce this, and Muftwin doesn't know what they did to cause this to happen.

Muftwin later discovered another method of creating what they call "ghost blocks", which is recorded in detail with reproducible steps in issue #25. In light of this later bug, Muftwin suggests:

"the groldy is primed to push the block as long as you are still in line on the next turn, but you broke the block. now the groldy is pushing nothing, so when the next block falls into place its a ghost because... ehh.
considering that i end up on the block when i do the bug i must be climbing and therefore its the same bug? the differences are interesting, but the essence is the same you end up pushing a block that isn't there."
