Still slow today ... after switching into the session (from Live on other session - also Firefox/HTML5), having to wait for the countdown to tick through before it acknowledges that a Workshop Production is completed. Not having the same problem in the Live session.
ETA: and then after collection, not acknowledging that and therefore not allowing start of next Production. Had to reload to get that started.
Well, I thought I would reload and get that started ... after reload, it was back to prior the collection with a minute to run. Collected again and this time, seems to be working?
