Further to wolfneuralnets's enquiry above, I'd also like to know if any progress has been made here?

The problem now occurs with such regularity for me that I habitually quit and restart OmniFocus every morning to ensure I'm not missing anything of importance.

I have debug messages turned on as directed in another post - as far as I can see (as mentioned by wolfneuralnet) no 'Due Soon' timer fires at the appropriate time to 'flag' due soon items. I'd appreciate any assistance as to what I should be seeing in respect of 'Due Soon' timer messages in my console log.
