Aug upgrade dupe glitch

[icleus]

If you have a full inventory and talk to smuggler's friend on the last visit to NYC you'll lay an aug upgrade. This happens everytime you talk to him to the point where you can spawn an infinite amount. I had three aug upgrades in my inventory when this happened.

Yeah, it's a known exploit that if you are going to get an item from a conversation but you already have the item and your inventory is full it will spawn on the ground. Doesn't happen if you have space or your inventory is full and you don't have the item already. We haven't yet been able to figure out what causes this.

It looks like the glitch's error handle is creating phantom inventory space. When the aug canister dropped from the conversation it also placed another aug in a "phantom" inventory slot #31. If I talked again it would drop the gift item while also creating a duplicate in slot #32. Very strange. You cannot see the extra inventory space for these augs but the aug tab says I still have 4 aug upgrades even though my inventory only had 2.

I emptied space in my full inventory and dropped the two augs, closed the inventory, and reopened it. Those extra slots with items, 31 and 32, were automatically relocated to the two empty slots.

Maybe there's two sets of code running at the same time that's not catching a conflict and the game doesn't know what to do so it just makes room to deal with it.

The <If inventory is full check> may not be catching a stack variable conflict. There could also be no clear check for when there is already another item in the inventory space. The game may not be able to discern between the two. Perhaps the game is making room by bypassing stacking into a non-stackable item and then forcing it out. Random guess.



It's been a long while since my deus ex editor days. I remember running into some weirdness with the code.
