[beta 11b] Created arrows stacking with unided arrows

[Grey]

Upon making a stack of 127 arrows it merged with 23 unided arrows in my pack to become a stack of 150 unided arrows. Either they shouldn't stack together or the new stack should be ided.

Not really sure what odd effect is happening, but creating further ammo adds to this stack, and seems to change the whole stack to the last created type. When IDing and selling off parts of the stack I found that despite selling several hundred arrows they were still ided as the most recent created type.

The stacking is normal, the stacking with unided is a bug
