Is anyone else having the ammo consumption of the ion cannon reverting back to its original state at random loads of the game or its just me ?me?

I keep finding my game randomly loads the ion cannons as they were at launch of the moxxi heist event. I been building a heavy flak crit build on my main and this is ruining my consistancy in my farming and playthroughs. Should have just lowered the damage instead of making this a thing…
