I don't know whether this bug is reproducable (due to lacking the fire starter to try it again). I tried to make a tin hammer, which consumed all three tin ingots and didn't give me a success or fail message. Upon re-logging, my inventory had a 'Decent Hammer' in it (with no mention of the material), with a sprite resembling a tin hammer. Any time someone attempts to equip the hammer, they're told it's broken and cannot be equipped.
Sessha just had a weird climbing bug where they ceased to be able to move at all near the top edge of the screen (not receiving climbing failure messages). When I relogged, they were one map north (where I'd been climbing toward) at the top edge of the screen, it was as bright as day (it was night or dusk when I started climbing; the website claims it's night right now), and they smoothly moved south the entire distance (through many trees) until they reached the bottom tile of the map. I can't move them at all. Also, I can see every tree when they'd normally be obscured; unsure whether posting a screenshot would constitute spoilers for that map lol
This was fixed on a second relog but I wanted to post about it just in case.
