I don't think we've ever gotten a bug like this before, so any details you can spare would be of great help!
- Which version of Grove are you playing on? (I'm assuming it's Windows 0.204, but just need to make sure)
- Is the game folder unzipped? And where did you place the resultant game directory file?
- Do you remember where you were, and what you did just before you encountered the bug? Was there anything unusual just before you saved?

The only potential fix I can really think of is to re-download the game, and import your saves by using this guide below.

Do feel free to list out any extra details that you can recount, and if at all possible, do you mind uploading the corrupted save file, the global.rpgmaker file and the persistent file somewhere for me to take a look at?
Thank you again for the report, and thanks for playing!
