Version

using cem-0.8.0 with forge 54.0.16 and optifine HD U J3 pre11

Describe the bug

I updated my mods and converted my custom resource pack from 1.18.2 to 1.21.4 and all the custom entities I made so far work as intended except for horses.

Screenshots

horse.jem in 1.18.2 working as intended:

horse.jem in 1.21.4, painfully obvious its vanilla, but you can see the custom pig and sheep in the background working as intended:

Desktop (please complete the following information):

• OS: WIN 10
• Java Version: 8 update 431
• Minecraft Version: 1.21.4

Additional context

My computer temp is consistent and frames do not drop nor does the game crash. I was shocked that the custom models work at all after the update to 1.21.4 (horses aside), but I have a feeling this particular issue is just a bug in relation to the minecraft version and forge/optifine version compatibility with latest cem (0.8.0); and I'm aware cem is not yet proofed for 1.21.4 specifically.

dingus moment, I think only a few mobs were working bc it was using old fabric install data despite me running everything on forge instead; so I downgraded from 1.21.4 to 1.20.4 overall, did a clean install for everything forge, optifine, and fabric related, then just relied on fabric w/ optifabric and cem horses works as intended again bc forge is the devil and so forth
