pocket's suitcase can continue to be exited by spacebar/other actions, however attempting to use spacebar appears to count as a 'double jump', consuming stamina, which will cause it to not exit the satchel if you don't have extra stamina (as well as wasting stamina for a simple jump).
similar thing happened this evening- ult'ed someone on the stairs and it glitched me to be under them- was permastuck and unstick/suicide commands did not work
confirming I also experienced this
expected behavior for this command is to only affect sensitivity while zooming. Currently there is no method to reduce the sensitivity while zoomed.
