The following bugs exist and are unlikely to be fixed for one reason or another.
1. Bins - Bins with many different kinds of items in them cause a too_long_eval bug, refuse to reproduce their items and generally act strangely. This usually happens with bins that contain hide or sewing materials, often small piles of different colors/pelts/cloth.
Solution: Trash piles of common stuff that is less than 10 units; it is usually useless for crafting. Split up supplies in a logical manner. DON'T KEEP ANYTHING YOU WON'T USE! The mud will be happier and you will be happier.
2. minor_imbed spell - After the focus has been drained, the trigger command will cause bug messages. Dropping it and picking it up again will fix it.
3. Inns - Innkeepers take your money but no time is added to the register. This occurs when you give the innkeeper enough money to cause an integer overflow in their brain.
Solution: Do not hand an innkeeper more than 60 suns or 20 rials at a time.
