[BUG] End Troll Boxes losing Items

[Xaikii]

Describe the bug
End Troll Boxes will lose some of the items if opened in hand.

To Reproduce
Steps to reproduce the behavior:

1. Get a Troll Box and place it
2. Fill 4 or more rows with items
3. Break it
4. Open it in hand
5. Place it again

Expected behavior
The items that couldn't be shown while opened in hand still being in the Box.

Screenshots
N/A

Debug crash log
N/A

Versions
Pandora's Creatures: 2.0.1
Forge: 35.1.7

Additional context
The items only disappear if the Box had been opened in hand.
Breaking and replacing it wont make the items disappear, but opening it will.

Opened in hand?

[Xaikii]

Is that not supposed to be a feature?
If so another mod seems to interfere here.

[andrew0030]

No they are like shulker boxes, you open them by placing them

[Xaikii]

Ok, then it seems like this is an issue of cross-mod interaction going wrong, huh?

Yeah from the looks of it that other mod is only intended to work with shulker boxes

Good to know, thanks for the help
