The server is using the newest worldedit version and the neweset spigot version 1.14.4

Long story short, this error is something that should never happen.

This is the piece of code that is causing problem: #114 int oldId = m_usedId.remove(session);

And in other place: #067 private final Map<EditSession, Integer> m_usedId = new LinkedHashMap<>();

So as you see this field can not be null. Of curse I tried to reproduce and stuff, without any luck. Could you check on the latest version? Do you have any additional logs (longer logs)?

I managed to reproduce the problem.

Should be fixed in 3.6.16
