I'm now using the latest version of firefox 3.0.
Every time you change your skin, you report a mistake.It is the player's health that is greater than 20.
I hope you can solve this problem.
The configuration file is generated by the plug-in without any changes.
The list of plug-ins is only the ESS Vault SkillAPI+ attachment.

I'm from China, and your "ChangeSkin", I like it very much, it feels great.The server USES some RPG plug-ins, so the amount of blood is more than 20, and the request fixes this "feature"The server version 1.11.2PS, of course, is the latest version.

Please follow the issue template

I'm sorry I'm here for the first time. Maybe I made a mistake.

Just post all everything to actual fix it. See this: https://raw.githubusercontent.com/games647/ChangeSkin/master/.github/ISSUE_TEMPLATE.md

i have the same problem, i have an item that increase player's max health and when i type '/setskin Feerko' many times my health always increase.

As always the question about your build version (sorry, but just to make sure) and how do you give yourself this item for testing.

I'm always using the newest version from github ;p

@Feerko Minecraft 1.11 too?

1.12.2
