So I was just playing nimbatus then I took a break for 24 hours and when I got back, The save file and the amount of time spent on the save file was still there but all my drones and upgrades disappeared (If anyone would tell how to spawn in the resources using cheat engine it would be greatly appreciated) (the Upgraded things was me attempting to use cheat engine (as soon as I changed the value the game crashed but reset my setium) I did this a few times to hopefully find the correct value but I didn't end up finding it)
