Not sure if there is any coding for locked/rusted chest.
The message still sends to chat and can be voted for, and returns the winner, however the item does not drop out.
NOTE: This was observed in Multiplayer and I am aware that it states that this mod does not work in multiplayer, however I have confirmed that it does mostly work with other players and works with shared items mods as well.
Was doing some testing, and all of a sudden the mod stopped working totally. Revoked Twitch access, and gave it back to no avail. All other mods uninstalled, and gave a new install of the game and it still does not work.
Mod worked for a while however it seems to break after a while, voting did not seem to register, current theory is that inputs that aren't options seem to break it but cannot guarantee this is the case.
Edit: After testing some more this doesn't seem to be the issue ^^
Some suggestions:
Create a config file capable of changing how long the poll lasts to adjust for stream delays.
Also in the config maybe setting a limiter on limiting how many voters?
Possibly make a command that refreshes the mod, and if possible can only be used by twitch mods?
