I got my first two adept mods (impact and counterbalance) from master vow yesterday. Today I was changing up the mods on one of my regular (non-adept) weapons and saw that my adept mods appeared there, but after equipping it, it got deleted from my mod selection. It hasn't reappeared in my inventory yet. It's just gone. Are adept mods single use or is this a really bad bug?

It’s a bug, you shouldn’t be able to use adept mods on non-adept weapons so it consumes the mod and you have to unlock it again.
