Has anyone else gotten this error?

[Willco2]

I was trying to load into a freebuild then I got kicked and got this error.

i assume its probably a error involved with a bike addon but im wondering if anybody else has gotten this error before
also i dont know if this is supposed to go in general discussion or off topic

I've gotten it before many times myself for the Deadly Train vehicle.

I dont believe I have that add-on, so I assume it's a server-side issue?

I've given this error loads of times.
It's what happens when a playertype addon fails to package its animations properly.
Your only hope is to get the addon yourself so blockland already has the animations.
