This is caused by this modification to Forge's classes. From what I can tell, there's two problems here:

  • There's no null check on the connection, so older versions of CC:T will also crash it.
  • If the connection is present, it's not guaranteed to be an instance of NetHandlerPlayServerBridge.

The simple bodge on our end would be to inline ForgeHooks.onItemRightClick or to implement bridge$getLastTryBlockPacketTimeStamp on our network connection. However, we should report this to Sponge and hopefully get it fixed there instead.

Reported at SpongePowered/SpongeForge#3060. Will track progress there instead.

I accidentally pushed a fix in 4c8fd4f. I'll revert when the underlying problem has been fixed.
