I am playing BG1:EE for the first time and while I am on the final level of Durlag's Tower, I had so many ammo that I wanted to add the Ammo Belt. So I added it using EE keeper. But the problem is, when i double click to select ammo amount while adding to the belt, the "to the container" button is grayed out. I can only select random amounts. Sometimes i can select 30 and i can add that. Sometimes it doesnt even allow 5. That happens when the container is empty so it is not capacity issue. I couldnt find that on internet so any help would be appreciated.


EDIT:
I tried to add the ammo belt using a cheat code on a much earlier save with

CLUAConsole:CreateItem("BAG05")

It still had the same problem so EE keeper is not the cause of the problem.

I created a bug report yesterday here .

How much ammo have you got in the bag, and how much are you trying to move? The total amount allowed is only 2,000 arrows, and to move stacks the game appears to need working space.

In the bug report I created above, I attached 2 screenshots. The bag (The belt) is empty and i am trying to select 80. Sometimes, it doesnt even allow 5 and sometimes it allows 30. The characters inventory has 8 free space.
