Mod not able to be reused from the GoS raid. While in the raid i got access to the resitent tether mod allowing me to take more damage while tethering. This got socketed in my (At the time) current chest piece. While continuing on i got a new chest with better stats and affinity of which i infuses up. I however have not got the resistant tether mod available for me to socket. This is the case for any armour regardless of affinity. I was under the impression that once we have the mod it is reusable and one of my clanmates has been able to reuse one of the other raid mods multiple times on any armour. (Please note i tried to socket this mod both before and after my other chest was gone)
