Occasionally, when I die (and respawn), one of the enemy bots will constantly loop the first few frames of its vertical sword swinging animation. I assume it's caused by it being in mid-swing at the exact moment I die.
This is a variation of a bug on file. One where sword robots swing wildly when targeting you. It's pretty easy to trigger on the Deathcube map just by running around all the Mark 1 Sword Robots in circles. - Thanks for the report! It's always useful to know alternate cases for unresolved bugs.
