So you most likely already know about this but im writing just to be sure.
We all know there have been some issues with sbh and its cloak. But when as sbh under 50 hp you lose your cloak but placing a nuke then enables your cloak again (not sure if other clients see you cloaked or not). I've been experiencing this one for a few patches now (not that I place a lot of sbh nukes)
Its not really game breaking but still a bug that should get fixed
