Creating World/World Corruption Issue in 1.14

[Former user]

Plugin version: V8.1.1

Spigot username: TheColdEmerald

Issue: Whenever I try to create a world in 1.14.X (Ive Tried All Versions with only multiverse, EWG, and worldedit) it always says “Cannot Connect to backend servers.” When i finally decided to try running /ewg createworld [the name] in the console, it came up with this:

Also whenever it makes a new EWG world on startup its usually always corrupted, or when you restart then it gets corrupted

Because that’s what happens 99% of the time when the paid dev fails to deliver as advertised.
