hi! this is super unusual as it's the first time i've seen it happen, so i'll have to ask a bunch of questions to try and troubleshoot it...
-first of all, locate your folder by typing %localappdata% into the windows search (if you're using a different device somehow, please tell me!) and find the lottylife folder
or look for it manually in C:\Users\<username>\AppData\Local\lottylife (replace <username> with your user)
-try to back up any saves you make progress in and see if they're still getting removed in real time while playing
now.. for the trial and error part:
-right click the folder itself or an empty spot inside of it and click properties, uncheck "read-only". if this doesn't fix anything, change it back
-run the game itself as administrator
-it may be kinda obvious, but if you're running the game from within the zip file then make sure to unzip it to its folder
i'm a bit late to this due to a power outage, but if you've solved it by now, also let me know so i can use the info to help folks out in the future!
