This has happened a few times to me now, on Void’s Edge with Kelvin only so far. It does not seem to be any particular item or what order they are purchased, but always the middle gear is un-buyable. I have tried remapping controller buttons before and after the bug to no avail. I can still purchase all turrets and wolf sentry upgrades. I have 2 twitch stream clips of the occurrence. The first of which, the server shut down on us and we lost all lore progress along with not being able to rejoin. Has anyone else experienced this before?
