Try dropping the stack of empties on the ground first, then move it onto the herbs. All the empties go away and you get 1 potion.
One thing I see that is wrong is that there is no check for failure on a move which won't allow the object to go back where it came from or to stack objects, as in the dreaded red X and being over your weight bugs I see posted. That is a simple thing to fix by setting it so the item drops at your feet in or in the nearest clear spot, or you can set up basic stacking rules and make piles which can be loads of fun and add a lot to a game engine as well. Stuff in piles can be hidden in plain sight so to speak.
One game I wrote (on BSD unix) had stacking like that and a fun stunt was to save curse scrolls you found along the way and put them into piles of equipment for people to find and get nailed by when they picked up the bait. Landmines anyone? Worked great for the more intelligent and greedy monsters. Makes for a nice way to start off an ambush.
Anyway, yes this was done with poison weapon and poison arrows, it happened both when they were both active and when they were used singly. Interestingly certain shot angles worked normally while others bounced. The ones that worked were pretty close to or right on the orthogonal axis lines, IE straight up and down or side to side.
I read the PM, thanks. I will check out the editor and see if I can change the same skills over to bows and see if it goes away and get back to you.
While it is interesting in an abstract sense to consider the how and why of these issues, it seems like things like this and the spells bug are pretty much make or break issues for people continuing to play the game.
After a while and a lot of invested time people just get fed up with having to fight against the game engine, which seems to be the rule rather than the exception with games in the last few years.
Almost makes me wish I was back in a research environment with a few million dollars worth of workstations on my desk..... :D
Ah, what gaming would be like if we all had a microvax running bsd unix.....
