[dough boy]

having another problem. when i try to connect to my server i get a connection lost error. goes like this

 

internal exception: java.lang.illigalargumentexception: the object block(ic2:sappling)(62e84527) has been registered twice, using the names null and ic2:sapling. (other object at this id id null{0})

 

Does anyone know how to solve this issue? already tried deleting and running it again (to get it back) but i always get this issue.

Upload the FML log (logs/fml-client-latest.log in the game directory) to Gist or Pastebin and link it here.
