I've already started a new game where I did dispel the rune and gotten the fireball spell. I'll just have to use that file then. If the fire spell really is that useful later on. Otherwise I'm currently travelling south in pursuit of the other travellers. Fighting slugs now. But I'm running in error readings a lot more often now.
Ah, that's because you're playing the game out of a OneDrive location, or you have some kind of cloudsync settings that are trying to make the game save / load to a OneDrive folder.
Due to the nature of OneDrive, it can cause the "persistent.rpgsave" to get desynchronised from the rest of the game. This file is constantly being checked / updated / referred to during the playing of the game and if it doesn't properly match the game's current state it will cause this error.
Anyway, the simple fix is to check where you have our game saved. If it's in your OneDrive folder, please move it out of there. If you have a setting where your files and folders are automatically synced to OneDrive, you'll want to disable that specifically for Grove.
that did the trick. I managed to finish the game. It was properly challenging all the way through. The supposed recommended level was 11 to finish the current built? I was level 16 and the fights were still pretty challenging. Final battle was a pretty fun guessing game of simon says. Had to make a small makeshift walkthrough of the options to win the fight.
