Yes, thats right

My High Mobility Multipurpose Wheeled Vehicle from ATOM_14_A's MCHeli expansion pack has found itself a new racoon hat

Its really funny but when you get in that seat it obstructs pretty much all of your forward vision, so is there a way to disable hats for certain mobs that...aren't mobs?

Update: its in all mcheli ground vehicles
As soon as you start driving the hat glitches out and stays where you spawned in said vehicle

Closing all issues as Hats has been rewritten from the ground up and the old mod for a long time now was no longer supported.. I'm sorry I wasn't able to address your issue. If you're still playing modded Minecraft, consider checking out Hats for 1.16.5+.

This issue might still be an issue I think but there's a way to disable this via JSON files which is what Hats uses for mob support now.

NGL This was a funny one, got a laugh out of me, so kudos for that!
