I am attempting to follow the tutorial http://www.minecraftforge.net/wiki/Containers_and_GUIs here for tileentitys and GUI's without any luck. The two problems i have are that when i run my mod and save then reload the world, my tileentity (tinyBlock) blocks wont save. The other problem is that i cant get GUis to open. When i right click my block (tinyBlock), the java console tells me that "A mod tried to open a gui on the server without being a NetworkMod"
Thanks for the help in advance:)
Here is my code:
