Crystal caverns spider tunnel
 

When moving in the area in the spider tunnel near queen dracnia, everytime you forget to babysit your pet for every meter of the way, the pet will warp straight over to the tentacle tunnel (I suspect even through walls) and pull one hell of a train.

It would be great to be able to fight spiders (silks farming) without having to worry about this all the time, as a pet class...

This is also an issue with the spiders themselves in the tunnels. If you don't baby them when you pull them around a corner they'll go through walls, fall out, and return with like 20 mobs from the TT arm.

To be fair, this isn't Velious-specific; I've seen it happen in lguk a lot too.
