Yesterday, while I was playing, several times I was affected by this bug when a piece of gear I already purchased started to be indicated like available for purchase again. I’m not sure if it got deactivated, or this is just a visual bug, but that piece of gear couldn’t be activated again (pressing 2 and then pressing according button done nothing, it kept showing up as available for purchase until I spent the credits and no longer had enough).
Not sure how exactly this happens (have suspcicions it might have something to do with the respawn, I was playing Incursion)
