Invalid horse

Several times when my horses have been put into a riding school it says invalid horse.It's not the same horse all the time but seems to be random.It happens when I go to the riding school and press complete.All the horses this has happened to have full tack are three years or over and 100% health and happiness.All are boarded in a stable.I've checked the bank and I am getting paid for the riding school but nothing comes up about stat gain or member experience.Could someone help me on this one please.

Hello! The invalid horse notification usually crops up if you click on a button more than once, for example if you're very quickly going through and completing your sessions and manage to hit one horse multiple times or hit another horse before the page loads fully. If you're getting the Money then you're more than likely also getting the stats, experience and possibly treats from it as well it's just not displaying for you at the time. 

I just finished a few of my horses in the Riding school and had no issues, but if you're worried about it not giving you the correct information check your experience and horse stats before completing next time and then after to make sure there was an increase. 

Hope that helps at least a little, if you end up having further problems with it do let us know!

Thank you .I,ll check the stats before i go to complete.I never checked them because I never know which horse it was going to happen with.If I'm getting the stats and exp it's ok.

it does it to me to, I get the stats and exp.
