Yep, that's right! The problem with older saves has been fixed. You can redownload the game and it'll work fine now. 

Somehow a newer version of Renpy snuck into the previous update and it's been causing compatibility issues. Thank you Colin EUMP for figuring it out and even testing the effect of a newer version! If I had you in my Discord, it would've saved so much grief :) Much appreciated!

Since I updated the engine, there's a chance you could run into something weird along the way. For example, I had to change outlines for names and in the menu. Feel free to drop a comment here or in the Discord if you notice anything.
