My suggestion - get used to it or reroll another AT.
Sorry, wish I had a better suggestion.
Have you used the "/releasepets" command? That's more helpful than the dismiss command from the menu, but not foolproof.

Yes, use /releasepets. Tha forcibly unsummons them rather than asking them to unsummon themselves.
It's almost to the stage where I wish they'd roll back the change - I'm not even using the ability of MM pets to zone any more and just resummon in-mission.
Thank you so much for the suggestion to use /release pets at least that gets me able to move on and resummon them again!
Much obliged 
Hello, I'm a new mastermind and I really like the Archetype but I'm getting a little frustrated and I'm hoping someone can give me some advice regarding the following issue.
More and more often when I try to travel somewhere using the trains or zone into a mission it seems my pets get stuck at the entrance and become totally unresponsive to any commands. I dismiss them and my pet window clears and states I have no active pets however the pets do not vanish and then become un-resummonable. My only recourse is to log completely out of the game and then back in and then resummon. Needless to say this is getting very tiresome.
Any suggestions?
Thank you for your time and assistance.
