I did a search of the forums, and google, and haven't been able to get any relevant hits. Everything I found was related to the stacking of abilities/skill points.
Back when the 1.69 patch came out, the server I was playing on ended up getting a bug where purchased items, such as healing kits, potions, or items that were picked up, would not automatically stack in the inventory. This meant that if you bought 15 healing kits, they took up 30 spaces in your inventory, etc. If you found or purchased 10 gems, they took up 10 spaces. All stackable items now have to be manually stacked. I've tried finding a fix for this, but to no avail. Has anyone had the same issue? I'm asking now, because the server was down for awhile, but has recently re-emerged, and is looking for a fix.
I don't know if it's something with a 2da, or the on item acquire scripts. I'm not really more than an amateur scriptor, and can only do some basic stuff. To help, there are no haks, aside from CEP2.2 I think, which will possibly be updated in the near future.
