Two thing related to names:
A small typo more than a bug, but "boar" (male of certain species) is named "board" under some circumstances. For example when you buy a male pig, it is named "board" when looked at or moved to (e.g. "You see a big board called Epsiloin-240 (leashed) here").
Additionally there is a crash when trying to name the animal with a special character. Specifically when trying a name beginning with ">", the game immediately exits.
