I think I found a glitch in Ultralisk Evolution

First part went normal, got the Ultralisks, mutated into toxic strain, fought out of the lab, got the scene of them smashing down the door.

Second part begins, get the warhead impact, they mutate into the Torrasque strain, I start smashing through everything. I get to the location of that easter egg with the Marine’s car, but when I attacked it, suddenly Stone’s portrait appeared and he said “hey, protect your truck!”
