Confirmation

• I have read the FAQ.
• I have tested the latest development build of Holographic Displays and the bug is still present.
• I have updated Spigot to the latest release for my particular Minecraft version.
• I made sure the bug hasn't already been reported on the issue tracker.

Description

It seem seems like that we're getting random null pointers in console: https://haste.cgsys.net/isonaziponiwafob.css
This errors comes by every few seconds or so.

We don't have non existing worlds or anything in the database.

How to reproduce

NPE should say enough

Server version

Additional information

No response

I've checked, that should not be possible normally, I suspect a plugin is invoking the API asynchronously. Can you provide a list of plugins that interact in any way with holograms?

If you download the latest dev build this error should go away, and if my hypothesis is correct you should get a different one.
