Hello, everyone!

First of all, i want to apologize if my question is too simple, but i'm freaking out.

After some months of inactivity (some technical problems i couldn't solve), i returned to the game, just to find out that i could only see two horses in my Collection tab - mounts. Same thing happened with my pets.

This afternoon i visited my house and i found out that all my mounts and pets are there but i can't use them in-game (or don't know how). I only can put them inside my house... but i want to use them while i play!! I mean, my Greymoor mount is cool... but i'd really love to be able to change it whenever i want (same thing with pets).

I can tell that all of my mounts and pets were in my collection tab (pressing U) before leaving the game some months ago. Can anyone tell me if anything has changed and what i have to do to use my mounts and pets ingame?

Thank you a lot! And sorry again for the "probably" naive question.
