Expected behavior

• Adding items to a stack in a Building Inventory should increase stack size.

Actual behaviour

• Stack size appears to increase, but interacting with stack sets in back to original value. Added items are lost.

Steps to reproduce the problem

1. Put 16 dirt in Builder's Hut Inventory.
2. Add 10 more to that stack.
3. Stack displays 26.
4. Click stack to pick up.
5. You are the proud owner of 16 dirt.

Does that happen only on the server or in ssp as well?

I've only tested this in SSP.

I noticed while playing The Pilgrim Pack modpack, but tested in an instance with only Minecolonies before I posted.

I was having this issue when using inventorytweaks sorting functions and shift-dragging to move things between containers. Lost a lot of fences/planks etc this way trying to restock builder huts.

I can confirm this on multiplayer server as well as singleplayer. Disabled inventory tweaks in mod folder, but problem persists. Shift-clicking anything stackable into Building Inventories will delete any items added to stack.

Example Repro steps:

1. Place 1 Dirt Block (or anything stackable) into Builders Hut Inventory (or another building inventory).

2. Shift click a stack of 1 or more from your inventory, all items shift-clicked from player inventory will be lost.

Variation from above report, after items are shift-clicked into the Building inventory, the stack size will increment for a split second then decrements back to original value.

I was not able to reproduce this behavior on the individual colonists inventories, shift clicking into their inventories works.
