Hello, I’m sorry to hear that. In version 0.2.4 the save engine was remade. The reason being for issues such as this. The old version of the save engine was something that was pre-built in Construct 3 (the engine used to make the game). However, for reasons unknown to me, this system had issues like what you described where people had their saves disappear for no particular reason.
When I made the new save engine there was a section of code made to pull old saves over it’s possible that there is a bug, but I’ve yet to hear anyone report one. So here is my guess. From what I’m understanding, if you open the game in version 0.2.1 you can see your save. If you open the game in 0.2.9 you cannot.
If that is the case then you may try this. I’m assuming you are on a windows machine, if not the file path may vary. You are looking for a folder called “VerdantVillage”. On Windows you can follow this path “C:\Users\USERNAME\VerdantVillage” where “USERNAME” is your username. That folder contains the new save data. Since you have yet to save your game on the new version it will probably be an empty folder, with maybe a config file.
You can delete this folder. Your old save is stored in a completely different place. With any luck doing this will force the game to go back through the save pulling process. Hopefully, it will show up. If it doesn’t I’m honestly not sure what to do, I’m sorry cause I know that’s a shoddy answer. This sort of issue was exactly why the save engine was remade, because the built in one seems incredibly volatile.
