okay so I think I figured it out. The code should be: public static CommonProxySovayCraft proxy;
IT works just fine single player as it always has. However, I get a new glitch server side. This glitch is based on some new code I worked out to create tameable monsters with all the special effects monsters get to play with. I have no idea why its just fine single but not multi. I could upload the whole thing but here is the error first.

I am using byte 25 to check if it can climb blocks which is currently not used by anything else that I know of.
this.dataWatcher.getWatchableObjectByte(25)
its the correct one. I changed the name from the one I'm using for my mod with copy replace. I have my mod temp named after myself and I didn't wish to share my real name. It lacks creativity, I know, but its in the early state of development. The mycraft names are interchangeable but I can find replace them again to make them more consistent if that would help.
All my mod adds is creatures at the moment. It works just fine in single player.

If that is not enough I can post an entity, model, and render file for view as well.
