Furniture does not rotate in "Home Improvement Television"

Description:

Furniture no longer rotates on our map, Home Improvement Television. This problem occurs on version 1.13.0.10 and newer (all previous versions it worked fine).

We have 4 models for each piece of furniture piece. The first has no rotation, second has 90 degrees, third has 180 degrees and fourth has 270 degrees. There is no model rotation in real-time. We just replace 4 variations of model one by one using a special tool for that we call the "Rotate Tool".

Our furniture models have many bones in their structures.  When attempting to rotate them, the whole model is divided into separate parts that levitate in the air.

 

 

Impact:

Unhappy customers, and rightfully so. Players cannot use a feature that is important for gameplay.

This affects not only Home Improvement Television but other maps we are creating that have similar mechanics.  Possible other maps on the Marketplace as well.

Repro Steps:

1. Download Home Improvement Television from the marketplace.
2. Locate or spawn in various furniture entities.
3. Try to rotate them using the Rotate Tool.

Observed Results:

Furniture doesn't rotate or rotates chaotically.

Expected Results:

Furniture rotates normally and in intervals of 0, 90, 180, and 270 degrees. 

Screenshots/Videos attached: Yes, see above.

Notes:

We think our only solution is to remake of all furniture (using only one bone for each model), but then the furniture will not be as detailed as it once was.

We have also tried to add an extra line in the model json file: "bind_pose_rotation":  [ x, x, x ] but this has been unsuccessful so far.
