Anvil crashes game

[Anonymous3-a]

When I use the anvil, the game crashes (presumably when the anvil repair overlay should get removed). I'm gonna look through the code and find the part that does that, so I can submit a pull request (that is, if I can fix it).

Side note: I got this from the mod on the Minetest content database, so if it's out of date, please tell me

possibly related to #18

@Anonymous3-a what do you mean crashes? can you post the stack trace (the full error message). even a screenshot would be useful.

Also, #18 is also the same problem as far as I can tell.
