Just did the Shipkiller mission, and found an instance where the beam never stops firing https://youtu.be/twLhUkZ8gRc
Another bug (display only) with exiting crewships (not railjack)
Enter Crewship 1
1st crewship leave animation/position displays
Once destroyed, C2 takes over
EDIT: I stand corrected on 2 counts for the bottom one. It happens with the base too (only saw on recent 2nd shipkiller mission), and it happened on a mission where this time I hadn't even boarded the crewship first. Nor was it a part of the mission to kill them. Not sure if there's any correlation.
