VictorSeven I deleted the previous copy, re-downloaded from the newly updated itch.io link, and tried again. Unfortunately, I also had the same problem again. I even deleted WCA's Saves folder from the system Ren'py folder, just to make sure it wasn't a problem with incompatible older save files. The game should act as if it's a brand new install. I also dug into the app contents and, while I'm not a programmer by any means, I couldn't find anything that looked to be missing anywhere. I even downloaded the PC version to compare the contents. (Once you get into the actual guts, Ren'py's program struc†ure is basically the same no matter the platform.)
It's frustrating because I can't tell what's happening at all. There's no Ren'py log, no system log, and no error codes, so I have no idea where to look. I can tell you I'm running this on MacOS 12.7.6 on a 2015 Core i7 iMac and that I've played dozens of Ren'py games on it (including prior versions of WCA) with no problems. Sorry it's being a pain!
