Versions

Minecraft: 1.12 Forge
Forge: 14.21.1.2387
MCA 5.3.1
RadixCore: 2.2.0
Issue Description:
I just downloaded the most recent version of MCA. It loaded with almost no problem. I say "almost" because when I encountered a village. I only see the shadows of its occupants. To test to see if another mod was the cause of the problem, I started a new world and logged in. After it loaded, I selected the option of living in a village, but when I went to move, my screen went black. My game didn't crash, and I can hear my footsteps when I moved around. So I restarted my game and went to try the same world again. The icon had a strange red tinge to it. I logged in anyway. Everything seemed normal. But the villagers were still invisible.

#917

I do not have this issue myself, just want to note this is most likely not a duplicate of issue 917.
917 affects Forge 2538+ while this report uses Forge 2447.

Also the issue itself is slightly different.
In 917 the villagers don't appear at all on client side (except sounds which are different packets), because the EntitySpawnPacket is not correctly parsed

However, this issue describes villagers being present on client side (nametags and shadows render), but invisible.

I have the exact same issue, and I am using forge 2562. At first the villagers weren't displayed at all (except the shadow and nametag) however now they have the balck & pink glitch but are still not displaying skins.
Edit: Downloaded a different version of forge, issue still occurs.

So I just tried to change the skin of a villager using the Villager Editor book that comes with the mod. And the game crashed. Thing is I closed it before it could give me a crash report.

I am experiencing the same phenomenon. In case
Moreover, it is red as it gets damaged.

Before I upgraded 1.12.0 to 1.12.2, these exact things were happening.
Now, in 1.12.2 I get this:

If I do anything with the Villager Editor, I get this:

I loaded the mod into the 1.12.1 minecraft version, redownloaded the Radixcore, and still no visible villagers. Just floating names. I did try the Village editor, and when I clicked to change the skin, it crashed.
