Oh, that's annoying for you :( We try our best to keep backward compatibility between old saves but as this game is so early in development major changes can sometimes make that difficult. Would you be able to send me your save file and I'll take a look and see what's wrong? Thanks
but i can tell you what went wrong, my robots will no longer put anything into the general storages and the production for everything slowed down. thanks for noticing my coment.
