Tested out with versions: 0.6.24a and 0.6.22a

Being nearby the friend changes my model in inventory to thier model, does the same for them.

We are using FTB: One, with additional mods.

We did not have this issue before adding mods, nor during the first wave of mods, and neither when performing a beta-test before adding a second wave of mods to the server, even then this issue started today, below are the mods we added in the second wave:

New mods

• Cosmetic Armour: Reworked
• Critters & Companions
• Equipment Compare
• Minecraft Comes Alive
• • *MCA: Reborn
• Steam Rails

Here's a list of the addons we put in as well, though i doubt any of these are responsible:

New addons

• Ars Novueau

• • ArsEng
• • ArsOmega
• • ArsAdditions

Clearing data, not having a model on myself but my friend has resulted in my inventory screen showing me with thier model.

No crash

• Edit: Friend tells me my vanilla model shows on thier model in 3rd person, and in thier inventory they have a vanilla model with thier own skin.

Adding a model, no crash on opening inventory, model switching continues, notable is that i can see their model disappear off thier body and appear in my inventory screen.

As soon as i look toward my friend, the model switching occours, at 3141 (thier position) and me at 3014 (my position) the model switching does not occour, but walking one block closer does cause the switching.

Seems to be render related

Update : I actually did end up finding a solution to this

The mod causing conflict with CPM was MCA Reborn. To fix the issue I went into the config of MCA reborn and edited the renderer line to block out any changes made by MCA Reborn when CPM is trying to change things

Found this! going to try to follow this method

Attempted to change the MCA config, render issue persists!

One crash, seems to be tied to if minecraft is still rendering the other model.

Found out how to fix it!

In the config folder, mca.json, near the bottom under 'playerRendererBlacklist'
add

"cpm": "all",

This will blacklist all rendering overrides that MCA will do for CPM.
