RedBelly glitch

RedBelly glitch (Spoilers maybe)
So I’ve come across a glitch that I couldn’t find mentioned and I’m playing in TVHM. I’m going after the signal source which is fine up to that point. After I clear out the enemies, I’ll run up to the gate, doesn’t open, then I’ll climb the building to the right side and jump over to the top of the gate. RedBelly will open the gate and the story mission will not continue as it should. I’ve verified my file integrity and that comes up clean.

As it stands, I can no longer proceed with the story. Any suggestions?
