I think it's more likely to be a problem with either a raw material or manufacturing process/equipment, to be honest.
Availability of Kolanticon has been on and off for a lot of the last decade, and it was unavailable for at least the last year that Peckforton had the MA. They were obviously unable to make it, and then they were bought by another company. Who knows how much of a revenue stream Kolanticon was for them, but perhaps that was a factor. The new MA holders would presumably face the same issues, and reformulating a licensed product would be very expensive and would probably take years.

tl;dr: I suppose the good news is that someone still holds the MA and can still market it in the UK - they wouldn't have applied if they weren't at least considering making it - but don't hold your breath. Hopefully your doctor can prescribe a suitable alternative in the meantime.
