EGPK - Ryanair departures

I seem to be experiencing problems with project AI aircraft, mainly ryanair at prestwick airport.

They radio in fine and taxi to the active ok. but then they just sit there at the hold short point and do not taxi onto the runway and take-off. I also haven't seen any traffic landing at prestwick either.

pls can somebody help

Its worth checking the airport out with Afcad2 as the taxi nodes may not reach the runway
Also,does Prestwick have ILS?if not try adding it with afcad2
