I'm currently seeing this bug often, after performing a Nuke, the character stands up and won't go anywhere. Attempting to jump, the character will glow while charging, then immediately stop when released. HUD is gone, and scrolling for weapon switch doesn't bring up anything. Game is still moving and acting around me, and I can still shoot the weapon in hand. Blackhole gun will drag me around and knock me over, but then the character stands unresponsive still afterward.
Save and reload works, though the problem crops up again.
