Archweapons unloading upon host migration

[XorUnison]

Host migrations are a notorious problem in the game, but recently I've noticed a bug that's new, to me anyway.

Sometimes host migrations in Archwing missions (this does happen in submersible Archwing missions too) can unload Archweapons. And I mean a hard unload, as if the weapon was never equipped to the mission in the first place. This means it is unusable, and doesn't get affinity anymore either. Also ALL previously earned affinity on that weapon is undone as well.
Say... I joined an Archwing interception, maxed out a previously unranked weapon, dared to stay despite the host leaving to level the other weapon... then I could get the maxed weapon unloaded and reset all the way down to unranked. Yes that happened. Not really a fan of it either.
