I encountered a bug where my character moves slowly, as if i had exceeded the carry weight even though my maximum is not exceeded (or even close). I can still jump and fast travel, but cannot run. I am able to run for a step after jumping. Does somebody know how to solve this? I tried to reload the saved game, but this did not work.
UPDATE: I am not in hardcore mode, i do not have crippled legs and there are no effects active.
