I will take a look at, pretty strange that 1.15.1 is based off 1.14.1 with a few 1.14.2 features. I will totally remove the 1.14.2 features and take the base engine to 1.14.1 with all the options I added.
I will post the Server Source once I get it to a state that will be stable.
Now I have all day to work on both the Server and the Client so I should make some head way.
