In Year 201, suddenly no mining instructions are being picked up. Everything else seems to be working normally.

My miners, hunters and woodcutters are mutually exclusive. I have about 15 miners, 3 woodcutters and 8 hunters. Not sure if the numbers make sense, but they are all different dwarves.

No red locks. No burrows.

The last thing I did before the problem happened was to assign a dining room as a tavern.

I temporarily fixed this by setting Miners to "Nobody does this" and then back to "Only selected does this".

However if wasn't long wasn't long before the same thing happened, and how nothing I try works.

Adding more miners doesn't help.

The game is now unplayable.

I have looked at quite a few things, with no good outcome.

Two of my 10 melee dwarves were also miners - fixed that.

I have a large surplus of iron picks.

Pathing is definitely OK - areas that were in the process of being mined successfully have stopped being mined.

Checked what my miners are actually doing. They seem to be having a grand old time, socialising, eating, watching guild demonstrations, meditating on jealousy etc.

I have let the game run for quite a while (>12 game days). Still no result.

I have tried what previously worked once: setting miners to "nobody does this" and then back again. Doesn't work.
