im loosing inoculatorcharges when theyr at max, usualy 2 charges at onces and often even start missions with missing charges.
Can't speak to starting a mission without them, but if you're losing charges and you're playing in season 2, then it's probably the warp anomalies. For instance:
Veil of Carnage: An unique Warp creation, this anomaly will follow you after interacting with it.
These effects aren't listed anywhere in-game, but it is in the compendium.
