Combat Master not tracking duration of conditions

I've been using Combat Master for a while now and never had this issue, but since today, Combat Master stopped tracking duration of conditions as well as not announcing turns in chat. 

I was having problems with Combat Master as well, something to do with forwarding the turn was crashing API the sandbox and giving an error.  I ended up rolling it back to the previous edition rather than the Latest one and that sorted my problem out.  Might be an option for you as well. API Heartbeat if you don't have it is a godsend for checking if the Sandbox has crashed when things aren't working.

Going back to older version fixed the issue for me as well, thank you for the suggestions!
