I recommend you back up your saves

I'm currently working on a fix to prevent future save corruptions.

In the mean time, I'd recommend people back up their saves.

It just means you're less likely to lose progress in a worst-case scenario.

You can do that by making a copy of the "EternityEgg" folder at

/yourusername/AppData/LocalLow/USERLANDS/EternityEgg

Hopefully I can figure out how to prevent future issues but I figured it's a good idea to remind people to back up just in case.

Thanks for your patience!
