[Bug]: Crash on Mob Conversion Due to Outdated Cardinal Components in Comforts 1.21.4

[northbanklew]

Minecraft Version

1.21.4

What happened?

Hi! im running Minecraft 1.21.4 with fabric, and I encountered a crash when conversions was taking place (eg zombie to drowned or villager to zombie). After some investigation, I found the crash is caused by an AbstractMethodError related to the ServerLivingEntityEvents.MOB_CONVERSION event, triggered by Fabric Entity Events API.

From what I can tell the crash appears to be caused by comforts bundling an outdated version of Cardinal Components API.

Crash caused by - org.ladysanke.cca.internal.entity.-CardinalComponentsEntity missing onConversion method

Crash fixed by - Manually installing the latest version of Cardinal-Components-API

Please it would be amazing if you could update Comforts dependency or bundled version of Cardinal Components API to version 6.2.2 for game versions 1.21.2-1.21.4 which includes the required OnConverstion implementation for Fabric Entity events.

Thank you for maintaining Comforts and getting it onto 1.21.4 - Its a great mod like many of your others! I look forward to hopefully seeing some more of your mods on 1.21.4 soon!

Thank you.

So sorry about that, looks like I forgot to update the bundled dependency. It should be fixed now in the 10.0.1 version I just released.
