Tons of Permanent Mounts Disappearing??

It is because of the item exploit i believe.

Some, like the Retro Scooter, were learned over a year ago.

I'm pretty sure he wants to know if mounts unrelated to the exploit have also gone missing seeing that some of the ones he mentioned don't even seem to be related to the item exploit; Shinsoo and Dragon mounts appeared to be among the ones exploited last week.
