Triggered tutorial text crawl on Exploiter Orb

[Doot__Doot]

I was about to start running the Exploiter Orb Assassination mission on my own, in a solo party, but as soon as I placed the thermia in the condenser to start the fight up, the red text crawl from the tutorial popped up, and left my screen black. I could still aim and shoot, but I couldn't see and was promptly killed by the orb. I then tried to abort back to Fortuna, but the esc menu was missing all of its buttons, barring the nightwave button. Because of the circumstances, i decided just to alt + f4 out of the game. I tried doing the Exploiter Orb again, and the problem didn't happen, so it must just happen every now and again.
