So, Skript seems to sometimes crash my server with no error but sometimes gives me an error

[StupidRepo]

So, sometimes when I am playing, my server just crashes with no error.

Skript gives me this error sometimes:

It seems Skript is crashing my server. Why is this happening?

It seems a Skript file is doing this so I will delete it and see if it makes a difference.

No it doesn't make a difference, I gave it 6GB of ram and it insta-crashes

Looks to me that you are attempting to run a delay when the server is shutting down.

ie:

on unload:
    wait 1 tick
    send "CLOSING" to console

something like this will throw an error.

This has already been reported a few times already, the only issue i can find right now is #993
Im going to close this as a duplicate as we are already aware of said issue.

But thank you for taking the time to report.
