Edit by @dktapps

This ONLY happens to servers run from Jenkins phars. Servers run from source are not affected. This indicates a preprocessor issue.

@iPocket he's banned from this organisation...

@HimbeersaftLP Would you mind trying running a server from source and see if the issue still occurs? We have reason to believe it's an issue with the phar preprocessor.

@dktapps It's NBT issue.
Let me try to find that commit...

[dktapps]

@iPocket It's because of a preprocessor inlining bug. In case you didn't notice, this does not happen if you build a phar yourself or if you run from source code.

[HimbeersaftLP]

Yup, when I run from source it works, when using a phar, not.

Also, I fount another old pocketmine forums link in the issue template, will you fix it, so I don't have to make a PR?

[dktapps]

I've disabled the preprocessor inlining to resolve the issue.
