In the en.us.lang, third row

death.attack.bledToDeath.player "=%s bled out

The interpunction " is in right place?
BTW, when I add zh_cn.lang into the mod file, both row 1 and 2 still show English, it seems that it cannot work? or just I did something wrong?

Yeah that's a small typo and fixed in the newest version. Thanks for letting me know.
