Hey ApolloHawke, Operator,
We managed to reproduce and fix it thanks to your input
You will see it as a part of a future update. We hope it isn't very disturbing in the meantime.
If it happens to you again you could try shooting or, as you pointed, using Hans' jetpack with the Hovercraft card / Mikah's decoy with the Fade to Black card as these will reset your stress meter.
Thanks again for your time and for helping us make the game better!
