Warning: Do not update to 1.0.3
If you have lag with 1.0.3 it is because of Fluxed Crystal. The only way to fix this problem is going back to 1.0.1 and the author of fluxed crystal does not seem interested in getting a temporary fix out as you can see on hes
twitter. So for now the only way to fix fluxed crystal is to go back to 1.0.1.
Also if you have been playing with 1.0.3 make sure check in your Material energy folder there will be
over 100mb of log files because of fluxed crystal being bugged and spamming logs.... had 1.2Gb of log files my self for playing for about 20 minutes
