Partner Rank: 1

Partner Team Reporting: Everbloom Studios

Verification builds: 1.8.0.4 Beta 26 (Win10 #1235442)

Summary: Item frames not displaying items properly. Usually not showing them at all

Impact: Breaks displays that we have setup to give player's information.

Repro Steps:
1. Load up a world
2. Put down an item frame
3. Put a custom textured item in the item frame.

Observed Results: Usually the item is not displayed. It is invisible. I did see clocks actually displaying 4 times within an item frame.

Expected Results: Items display properly in item frames

Screenshots/Videos attached: Yes

Regression Builds: 1.7.0.13_RC4 (Win10 #1217941)

Notes:
While I primarily saw this with custom textured items, I also saw it occasionally happen with default textured items. (Clocks)
In the picture below each of those item frames has a custom textured sword in it.
