:( It just happened again...
So every time I go to bed and shut down my pc i will lose all progress I have made...
Ps I play on the Opera Browser if that helps anything ;)
I do not have that option activated, as all other games that also use the local storage still hold my save...
Another thing I found out is, that when I duplicate the tab it gives me a fresh save. But if I first made a manual save it sometimes gives me the same as the save of the other tab....
But okay thanks for working on a save system with export/import ;)
