We've got a rasher of quick fixes for stuff that was broken in Update 51 earlier this week, including the following.
[list]
[*] Scoring bug for versus fixed
[*] Ep4 finale generator sounds work right but are still too quiet
[*] Damage radius on some fire in the Ep4 finale reduced
[*] Several more Ep4 spawn areas that are invalid were fixed. Please keep sending these in, it’s hugely helpful
[*] Removed the reference cube from Ep4
[*] You’ll see titles on other players when you join in progress now
[*] You should see hitmarkers on kills for common again
