Marking and Coat Randomizer

I used a marking and coat randomizer on one of my horses - he was a bay with a star before - and after using both randomizers - hes gets bay and a star...looks the same as before nothing changed. Is this just a risk you take using those randomizers? or is this a bug? Its almost like nothing even happened/changed when I used them

Thank you :)

He must have been carrying Gg or GG, in that case when you use a coat randomizer they can stay bay but will be gg. Marking randomizers are used for patterns such as splash, sabino, etc...unless you meant face marking randomizer? 

Hi Riverwind, 
Looking in your userlog it looks like he did change from Grey over Bay to plain Bay, whcih would not be visible as a foal. His  face marking changed from Interrupted Stripe to Star. You can see the genotypic change in your user log located at the bottom of your homepage!

Oh okay!! Thank you both :)
