Prerequisites

• I am running the latest alpha version of MineColonies and Structurize for my Minecraft version.
• I checked the MineColonies/Structurize wiki and made sure my issue is not covered there.
• I made sure that this issue is not a duplicate of any existing issue.

Context

• Minecraft Version: 1.16.4
• MineColonies Version: 0.13.452
• Structurize Version: 0.13.96
• Related Mods and their Versions: Forge 35.0.18 (Using the official modpack)

Expected behavior

Stacking or placing items in their inventory should not disappear.

Actual behavior

I am noticing that food sometimes disappears when I shift click (to stack it upon existing food) in their inventory.
It justs defaults to 1 food when I add like 40 ish of that food type.

Steps to reproduce the issue

1. Access the inventory of a random citizen
2. Add 1 (eg. carrot) to their inventory
3. Shift click multiple carrots to their inventory.

I found another way to reproduce it: (best way to show the issue 😄)

1. add a stack of something to their inventory
2. right click the items to split it in 2x 32
3. add the 32 back to the original slot to get it back to 64.
4. after doing that a few times, you'll see the items vanishing

They don't always disappear. Sometimes you can just put a maximum of 1 type of the same item in their slot. Not only does this happen via shift, but also when you try to drag in their inventory!
