Bug Description: Having a Badge Case in your hot-bar while previously having it opened caused items in the inventory to move to their original position before the case was opened. For example, moving a pickaxe from the hot-bar to the main inventory will move the pickaxe back to the exact space in the hot-bar after clicking on most block entity that has the ability to be interacted with. So far, Healing Stations, Pixelmon Anvils, and PC's don't cause them to move. Although, Apricorns plants (which don't have an inventory slot) do cause items in the inventory to move. Attempting to throw items on the floor with the "drop selected item" button does nothing and no items are dropped. Dropping items out from your inventory with your cursor makes the items doesn't drop the item, but makes the item disappear from the inventory until you click on a block, as mentioned before. Attempting to pick up items from the ground that aren't in the inventory will result in the item not showing up until you click on a block, same thing. If you do have the item, the stack doesn't update until, again, you click on a certain block. I'll note more as a reply.

Steps to Reproduce:
1. Have a Badge Case in your inventory. (Might require a badge to be inserted inside the case. I believe the colour doesn't matter.)
2. Open the Badge Case and close it. (Have the case registered.)
3. Everything in the description will occur.

Expected Result: After closing the case, items should move around the inventory without incident.

Actual Result: After closing the case, items are moved to their previous location in the inventory after interacting with certain objects.

Notes: This has not been tested on other Launchers. Only Technic launcher has been tested to my knowledge. This bug may relate to a previous ticketed bug, "Badge Case Messing Up Inventory and Bar". It's possible that this bug could be caused by the Badge Case having a save of some kind that makes the whole inventory saved. This bug likely occurs with BoP (Biomes O' Plenty) active and will probably happen in different difficulties. I'll update this when I get around to bug testing this mod-pack again.

Another Smaller Note: If you're wondering why I made my bug report in this format, it's because this is how QA Testers in big companies have to write a bug report. Class "A" is the most severe and need to be fixed as soon as possible, while class "C" is a small bug which can be fixed later. Sometimes, a class "D" report is used as a suggestion. Also, I'm free for "hire" as a bug tester for you guys. No money needed.

I should state that I talked with XpanD about this, he wanted me to post a ticket since he had to sleep.

Thanks for the report! I've now tested this myself, and can confirm the issue. Since this seems to have the same underlying issue as the one reported over here, I'm going to mark this ticket as a duplicate. Keep an eye on the other ticket to see the issue's status.

(I have added all of this to the internal ticket, some good info here!)
