Steps to reproduce:

1. I am testing FC 1.4.3 and I am using both the latest files available to me as you can see above but on existing worlds, I am getting a server only crash whereas it works fine client side with an existing world

load an existing world with projectE and chisel and bits

What I expected to happen:
it to not crash on world load

What happened instead:

the server crashes with the report above

I am also reporting this to the Project e team sinkillerj/ProjectE#1719

It looks like initial EMC Calculations, and Initial Bit Determination are compounding when your server is loading

You can adjust this with max-tick-time inside of server.properties, apparently -1 disables it entirely.

That worked great thank you for the suggestion i have also added this solution to my changelog for the pack so people can do it on their servers aswell.

thanks again
