Im having same problem, glad its not just me, i want to play so bad, had about 27 hours into my save file...id just start over but i feel same thing will just happen again. but such is alphas.

I found a save file that will open and let me save and auto save...its only a few mine before the first save i posted yet only 19megs. the only thing i did between the two saves is set up a new iron mine. here is that save https://www.dropbox.com/s/tbgou7guka30c16/har8.zip



>>>EDIT

Never mind ...

I have plenty of space, here is my save game https://www.dropbox.com/s/sxh7796ikmd9m3o/JIC.zip

"Couldn't read input file" my game will no longer auto save's and most wont load, game just crashes.
