Mastermind Thugs pets don't display upgrade equipment costume after changing zone.

[doctordelirium]

With Mastermind Thug pets, if you have them equipped with both upgrades, when you change zones it reverts their costume to as though you only have one of the upgrades. They have equipped both upgrade's powers, however it just doesn't show in their costumes (e.g. Enforcers only have leather jackets instead of trench coats). 

 

If you give your pets either of the upgrades after you zone it will show them with the correct costumes again.
