I'd like to thank the Galaxy-Craft community for a great year! Happy New Year, and here's to another year of fun!
Maps from the 1.5.2 pack will not be compatible with the 1.6.4 pack, the only exception being the server map. I'll update you all as I make progress on the update, and I'll release the 1.6.4 pack once everything is fixed with the configs. Once again, Happy New Year everyone!
EDIT:
The server is now working, and all the ID conflicts have been ironed out! The pack has been updated to 1.6.4 publicly, so go and download it! The staff and I will begin sorting through people's inventories and fixing any bugs we find. Stay tuned for more updates.
2ND EDIT:
The server is now open to the public! Anyone who is having crashes at the Mojang screen should set the amount of memory to use in the launcher to 2GB.
