I downloaded the update through the Twitch launcher, and get an invalid version error in chat on world load.

Whoops, forgot to unset that in the code. Sorry about that! The version is valid, but I put that in there for debug purposes so it's not used when it shouldn't be. Will get that fixed ASAP. Thanks bunches.

Alright, new version here -

Thanks for letting me know!!
