Thank you for the feedback!
That is a bad bug, not the kind we want :D. I’ll see that it gets fixed by the next version.
In version 0.80, the loot drop from fights will be ensured, so you will always have between 1 and 3 drops per win :).
I don’t think the base difficulty will change for now, but I may increase the damage and defense values of the items if the difficulty of the encounters is still to high, depending on feedback.
