Unfortunately version 0.24.0 was a big rework of the 1st act of the game and there is no patch to get you from 0.23.0 to 0.24.0. You have to redownload.
There should be version 0.25.0 in 0-14 days (leaked patreon version) and there should be a leaked patch available too, but no guarantee on that. You might want to wait for that before doing full download in case of no patch leaked.
Hah! Alright.
Thank you VERY much .
