I have noticed since latest patch i am getting some green 'p' next to horses in the declarations page what do these mean?
the horses that have this have nothing in common some are unraced 2yo some older horses none are been retired
And a small 'c' in a grey circle has apeared from time to time?

Grey icons will be pacifiers

c= Cheekpieces
v=Visor
b=Blinkers

Not sure what the green 'p' is as I haven't come across it before.

A green 'p' should be only against horses who are due to retire to the game pool.

If the 'c' is against horses who are entered in races that means that they have won on the course before. Sometimes you get a 'd' here which means the horse has won over the distance. Sometimes a 'g' on the race day which means the horse has won on the ground and sometimes you get 'cdg' which means the horse has won on the course, over the distance, on the ground. If this isn't it then where is the 'c'?

A 'c' in a grey circle means cheek pieces as GG said above.

on the declaration page its ramdon horses all the time it not distance going or anything like this when you are entering your horses for a race check out after the horses name before it entered
