This used to happen occasionally, but lately happens more than 50% of the time.
Several of my 'toons have more than one horse.
I go to a stable and access the stablemaster.
I look at the stats, (makes no difference whether I add a stat point to the 1st horse or not) and swap to other horse.
Crash to desktop more often than not.
OK, what kind of bug do I report?
The problem with society these days is that no one drinks from the skulls of their enemies anymore.
