I know you don't intend to support 1.17.1 any further, but I believe this constitues a major bug within 0.9.1

After some testing with a custom resource pack, I noticed that all custom textures would work, except the ones applied to spawn eggs.

I have no idea what could be the cause of this, but in testing between CITResewn-0.9.1+1.17.1 and the newest Optifabric version, CITResewn did not apply any textures to Spawneggs, where Optifine did.

I am willing to fix this myself, if some pointers could be given, as to why this can happen.

Example properties file for spawn egg:

type=item
matchItems=rabbit_spawn_egg
texture=bowblade

I'm sorry but I disagree, I don't think this should be considered a major bug(or at least major enough for me to bother with v0.9 again).

But hey, that's what open source is for! If you or anyone else wants to fork and fix this, go ahead.

I'd assume spawn eggs just handle their textures differently, haven't checked their code yet.

No problem! I might take it up then.

Will the spawn egg problem be fixed in newer versions as it persists? Then I will wait for that and try to backport the logic.

Probably, I still haven't taken a look so I don't know exactly where it broke.
