Villager entities get rendered as white or pink dwarf faceless dolls, as in the pictures below:
(before updating architectury to 4.9.83-fabric):

(after updating architectury):

I'm testing this under the Aternos online server. I cannot reproduce this when hosting on my local machine. What could be the issue?

client side error:

For me this looks like incompatible versions, double check which version the server and client is running at

Server:

• release 1.18.2
• Fabric 0.14.9
• MCA Reborn 7.3.17 (fabric)
• Fabric API 0.58.0

Client:

• release 1.18.2
• Fabric 0.14.9
• MCA Reborn 7.3.17 (fabric)
• Fabric API 0.58.0

Hmm, should be fine. I assume the server restarted properly after changing mods?
Please send me both server and client logs, either here or any DM, so I can try to track that issue down.

I'm happy to tell that this behaviour ceased after I updated other library mods from the modpack list.
