I am new to reporting bugs about games so bear with me as I learn the lingo and best methods for reporting them for Hexxit. Thanks!
When my mouse hovers over a Keese, the name in the top center information area is "entity.zeldaswordskills.keese.name". The information with the mob picture on the top left has "Keese" for the name. When I am killed by the little bugger, the text in the chat section(?) is "AzureDragonfly was slain by entity.zeldaswordskills.keese.name".
Hope the info helps!
