Inventory Item stacking

[Semipalmated Plover]

I'm finding this really annoying... i picked up 2 arrow shafts and they stacked in my inventory, i right click and split them up in my inventory and they won't merge again?

I can split my gold up and it'll just drag back to one stack.

Also i've got 2 fireball scrolls in a stack that won't merge again after splitting them...

What's going on here? How do you stack these things in your inventory?

Do a sort by type and that usually restacks them.. Also you can pass to another character and back to restack. Some items apparently have slightly different codes and won't stack no mattrer what you do but if they were stacked before they should restack.

Thankyou for the reply.
The 2 fireball scrolls will re-stack with those methods but the arrow shafts won't (when previously i had them stacked when initially picked up). I've also got a 3rd fireball scroll now that won't stack with the other 2 with either of those methods.

I'm only on the initial beach scene and the inventory is already doing my head in!

Items that look identical might not be identical internally.
One item might have a script attached to make it hidden and appear when a character with enough perception approaches.
To the engine, those two items would be different things and the engine does not know that a script attached to an item will never be needed nor executed anymore after the item has been discovered, so it keeps the item separate and does not allow stacking other items with it.
If it allowed stacking, the script would be lost.

So basically if the engine sees internal differences between objects, the objects cannot stack because those differences would get lost.

There are fireball scrolls in the tutorial dungeon and as far as I remember one of them or even both are flagged as 'public objects' (this has to do with the story scripting system) when normal fireball scrolls are not public. This is enough difference for the engine to not let the tutorial scrolls stack with regular scrolls. (Actually, the engine MUST preserve all properties of the public scrolls because it does not know if any story script will use the scrolls in the future.)
It's purely internal, you won't see any difference between them in the game, only that they don't stack.
