[1.7.4] Quantity of equipped alchemist gems not visually updated when equipping more

[ScienceBall]

If you:
1) have some alchemist gems equipped (in your ammo slot), e.g. 50 alchemist onyx
2) use Create Alchemist Gems to create more of the same alchemist gem in your inventory, e.g. 70 alchemist onyx
3) open your inventory and equip the new alchemist gems (the stacks will merge, so you will have e.g. 120 alchemist onyx equipped)
then the ammo slot in your inventory will not visually update immediately, and will still show the old number of alchemist gems equipped (e.g. 50 alchemist onyx). The HUD ammo count is not affected by this bug and will update immediately. IIRC, the ammo count in your inventory will be updated if you close your inventory and re-open it.

I have heard that there are plans to get rid of alchemist gems when reworking Alchemist, so I am aware that this is probably a low-priority bug.

EDIT: The correct number is shown in the tooltip which is displayed when hovering over the equipped alchemist gems.
