Murder Gamemode Error 'WriteDouble'

Hello I know its wrong to have my first post asking for help but I currently am getting this error on my murder server and am looking for a fix.

[ERROR] gamemodes/murder/gamemode/sv_rounds.lua:32: bad argument #1 to 'WriteDouble' (number expected, got nil)
  1. WriteDouble - [C]:-1
   2. NetworkRound - gamemodes/murder/gamemode/sv_rounds.lua:32
    3. unknown - gamemodes/murder/gamemode/sv_player.lua:19

Figured out it was from an addon thank you!

Post code.

Posted! Hopefully that helps. Also to note other addons cannot detect that the round has ended.
