I've been having to restart my saves every time I play again, as it seems the more turns have gone by, the less likely I would be able to access it.  I have save files where it only has around 10 turns and they will load, but not larger ones. When I click on my saved maps the button goes a dark grey, and back to white. Does anyone deal with this? And if so do you know how to fix it?

I have the same issue, sadly i have no idea how to resolve it.

yes i am also having the same problem 

Save load fine. Just can't draw a card after it loads
