Got it.
I just checked code on the master branch, the bug is still there.
Just fixed it.
Thanks :D.
And you can edit the value to "3" to restore hard difficulty.
ok, glad to know its fixed. If I increase the value to above 3 will it get harder?
Nope.
Difficulty value ranges from 0 to 3, representing Normal/Peaceful/Easy/Hard respectively.
