Xbox Series X Class 801 Broken After Second Winter Core Update

Hi.I have noticed that since the recent update the Class 801s on passing AI services are not loading in as complete trains in some areas on East Coast mainline.For example you might get the first 3 coaches the nothing then another coach and then no coaches or end driving trailer.
I've also notices the 801s now sound terrible when passing the free camera at speed.
