im sorry, but take a look please
i set drakes to "disable"

and i still get them summoned

same with usual flying mounts

upd: i just found why,
so when i make any rule with mounts like this

priority stops working, is it intended?

okey, i get it now, i have to set it to

instead of random mount

Exactly right!

This is in the documentation but I'm going to add some tooltips for a coming release.

Happy adventuring, X.
