Using Fabric port.
Version: guardvillagers-2.0.6-1.19.2

Literally I'm just facing the dude and he ain't shooting me

I still have the same problem in the new version (guardvillagers-2.0.7-1.19.2) so I guess it wasn't fixed ?

Crossbowmen work for me, odd...

The problem come from me then but I have absolutely no idea of why it doesn't work :(

I've seen them shoot mobs.

@omeggga Really? In that version: guardvillagers-2.0.6-1.19.2 I found that crossbow people don't work at all. Yes they perform the animation of shooting the crossbow but no arrow actually comes out.

Also I remove every other mods that I had and the problem persisted so...

Me too but strangely if you give them a bow it works, so I suppose it's just the interaction crossbow-guard that is problematic.

Hmm so exclusively crossbows huh, ill check it out

the crossbow works when I put infinity into it (using universal enchants mod) and give it to the guard villager, but still doesn't fix the problem itself. Initially I thought the guard has no arrows on it's inventory, so I gave some to it's offhand, but still doesn't work... so I don't get how infinity on crossbow works.
