Actually the entire mod is. I Disabled invul and It was still rapid spam and kicking me.

latest.log <- Server log

Thanks for the report.

What leads you to believe this is an Essential Commands issue?

I see SkyfallSpawnHub.syncSkyfallDeathProtection in the direct trace. The PAL maps mantion EC because the EC-bundled PAL version is being used (probably due to being the latest version on your server, not sure)

If you remove EC, do the errors go away?

[Typhewn]

I removed your mod and everything is literally running perfectly fine and I've been using my mod skyfall through months of refining like there's realy 0 isues when essentials isn't present. you can see the invul in the log as well.

I can send you that modpack without essentials also for you to see yourself through discord If you'd like. If it is skyfall my bad for the false alarm but I highly doubt seeing as everything was running smoothly and even chatgpt told me i needed to remove your mod specifically while I was bashing my head against a wall trying to figure out the issue I got rid of a few mods and essentials was one I really wanted to keep but was on the removal list.
