@0999312 has found lots of bugs like the server crashing, Mobile Suit models render incorrectly, and the Mobile Suit inventory glitches items.

Server crash by java.lang.NoClassDefFoundError: net/minecraft/client/entity/EntityPlayerSP
MSEntity Rendering error
MS Inventory can't work properly
MSEntity can't move
NO HUD
Can't call MF
Invaild MSEntity
Dimension Loading too much time/Loading NPE:
[Server thread/FATAL] [net.minecraft.server.MinecraftServer]: Error executing task
java.util.concurrent.ExecutionException: java.lang.NullPointerException
How to moon and another dim?

The moon and other dimension access will be added in a new "autopilot" menu that is accessible in the Mobile Suit's interface.

MSEntity can't move, MS Inventory glitches, and MSEntity rendering are all known bugs and haven't had a patch. We will work on fixing the server and NullPointerException and any bugs that prevent the game and world from opening first, then we'll fix the bugs in order.
