I have no idea why, but the tile in the middle of the screen doesn't get claimed by my imps. It had one of those imp-speeding-up things on it but even then my imps would not claim it.

Thanks for the save files and details. This sounds like it'll be a pretty transient error so we'll likely only catch it in a save file. I'll pass this through and we'll investigate when we have the chance.
Unfortunately I have an hard time to fix.
I see the tile is there and has no claim task but what I would need to know is how it got to this state.
Some error must have prevented the creation of the claim task, but I do not know which error and how it happened.
