[OmeletPanM33]

I am so apologize to repost a same issues . Since i get a Duplicate tag on my issue #948 and it is been closed ,but i din't found that which issue i duplicated. I like this plugin , I like mypet , I like to ride, but these kill my server. Please help me fix this.

Bukkit/Spigot/Bungee Build/Version:
Spigot 1.11.2
MyPet Build/Version:
MyPet-Premium-2.3.3.jar
Do you use the premium version? (this wont change anything for you)
Yes
What is the expected result?
