Transference "Scream" sound immediately after finishing The War Within

[Boneframe]

Immediately after completing The War Within mission for the first time, activating transference while on your ship to enter the operator state you can hear the "scream" sound just as you would hear when activating your focus power previously in a mission. 

I took a video/audio recording: 

 

I restarted Warframe and the sound no longer played when doing this. I figured this wasn't normal and wanted to help point it out. While it's not troublesome, I figured you guys would want to flush out every little spot when possible, including this very minor "bug". I enjoy the game, thanks for all the hard work!

P.S. The sigil "Mastery Sigil" on my operator doesn't reflect the icon for MR5 (which I am) which is shown in the video. Not a sound thing but figured I'd give it a mention.
