Passport Lost with Valid UK Visa - Applied for a New Visa [closed]

I was issued with a standard visitor visa (Business Visit Visa Category) which was multiple entries and was valid for 6 Months.

Unfortunately, I lost my passport in London (I live in Pakistan and was in London to attend the conference). I reported my loss to Met police where they provided me with the reference number only and no paper report, then to get the emergency travel paper I reported that loss on ReportMyLoss.

I didn't overstay and returned to Pakistan as per my planned dates. On my return, I filed that incident to my local police station to be sure that I don't get into any trouble.

Now I just applied for a new Business visit visa. Had I not lost my passport, my current travel plans should have been covered by the validity dates in my previously issued visa. I believe this will support my case.

I sent all documents I had including Oyster card slip, Local Police Report, ReportMyLoss Report and photocopies of previous visa and passport and other supporting documents.

Did I follow the right steps? What possible issue ECO can highlight to reject my application?
