Thanks for the HF. Still having tons of affinity gain issues with archguns in Orphix Venom though (literally done like 3 missions to the full 36 orphix rounds with a Fluctus, with a booster, weapon still rank 9 lol). Archgun affinity gain still seems to be broken.
Having this bug too. Tried to level my fluctus several times and it's still only Rank 8 (despite having an affinity booster). In mission it shows a higher rank and then deranks after. On top of the usual bugs (crouch bug, not being able to use abilities bug, etc on random). Extremely frustrating,
