I added RandomCoords to my server today and ever since the server contains lagg spikes. Nothing else has changed in the past month, however. Might RandomCoords be causing those spikes when someone uses /rtp ?

Timings may be able to help you/me see what the issue is here? Could you post them?

I believe they don't say anything about this plugin. https://timings.spigotmc.org/?url=casodusate

From that it would appear that my plugin is running smoothly.

Was thinking the same, didn't do timings on the time of the report. But since it are lagg spikes which never really occured before, I thought it maybe occured when someone uses /rtp.

Maybe run timings for a bit longer while the lag spikes are occurring and I can see if it's my plugin and diagnose from there.

The current timings I sent contained a lagg spike of around 15 seconds. I will check next time. Thanks!

From those timings I can tell you there is a lot of entity lag, Which won't be from my plugin seems to be world2?

Entities are quite nerfed using React, actually. So much that it impacts gameplay too. But this has always been showing up in my timings and those lagg spikes are new since yesterday.
