Shift returning back from ferret, sometimes leaves you with about double the amount of hp's the ferret had.
Human Form = 500hp
Shift Ferret Form = 25hp
Shift Return Human Form = 50hp
Shift return back from dragon to human form, nearly always looses 50hp's, if you were full in human form before you shifted.
Human Form = 660hp
Shift Dragon = 1450hp
Shift Return Human Form = 600hp
On a few occasions I have quaffed potions in inv, like mobs do? I've checked my scripts for quaff scripts and I have none.
Sometimes mobs suddenly die, IE, in 5-10 rounds shorter than the duration you'd expect. I once killed the pale lantern fish in murkwood in 1 round without using breath weapons. *flex*
There is a strength bug on occasions, when you shift and unshift, all of a sudden you can't pick stuff up anymore. You have to rent and re-enter the game.
