(Yeah, I'm using a custom PaperSpigot 1.7.10 fork)

Config:

Since 1.7.10 is such an old version, I don't provide any support for free.
You may choose to either buy the plugin, or submit a pull request to get this issue fixed :)

@Techcable I was going to buy it after testing the plugin.

Welp, time to get my hands dirty then.

[MrPowerGamerBR]

...or maybe not, I will try to get a bit of money to buy SonarPet, but, after taking a quick look, the issue is on the PetConfig, because there isn't a separate config for every version.

He knows the issue (its pretty obvious).....
He just doesn't want to waste time on it until you pay him.
