So, I have been having an issue with my copy of Saints Row IV when it comes to the Thumpgun. I am well aware that the weapon goes into the shotgun slot of the game, but I am currently having a hard time with the upgrades to the weapon. I'm sure I once had been able to upgrade it for a time, but many months ago, the weapon just lost its place in the upgrade section. I believe that it had started when I had acquired the GAT V pack for free on the day it had been released on Steam. (It was free on day one.) So ever since I had gotten the DLC, I could no longer have it appear in the upgrade section. It also cannot be purchased in Friendly Fire like the game is supposed to. I know for a fact that this doesn't just affect me, because I once played online with another Steam user months ago and I asked if they had the Thumpgun available in the same selection system yet they also had the same issue, though he didn't mind as much. Is it possible that is bug could receive a well needed patch? Because I always wanted to be able to change that Zin weapon like the rest. Also I think that bug only affects the AU version since mine is the "low-violence" version. Thank you.
