Restarted game with v 0_8_8_4. When poison wears off, while walking around, the name is omitted, so it just says " is no longer poisoned." (Let me know if there's another place you'd like comments posted.)
Thanks for the report! I'm aware of the issue. It is caused by one of the obfuscated plugins, so I haven't come up with a solution yet, but it's on my 'to do' list. I'm most active on the game's Steam forum and in the dungeon crawlers discord server, but Itch.io comments reach me also.
