Ah yeah, I have heard the autosave slot doesn't work as expected as a normal save slot. I will take a look at that.I had no issue with the 0.18b.
I'm now wondering if i tried to import it on the autosave slot by mistake, which might have been why i was not able to load it previously.
It functions when using the second or third save slot, i managed to load it but at a snaily sluggish pace.
