Describe your problem, including steps to reproduce it

1. place down a pneumatic dynamo
2. open the GUI of it
3. click on the "output" tab
4. the game 'crashes' back to the main menu (actually the mulriplayer page. even when tested in single player)

Any other comments?

That stacktrace isn't related to the dynamo in any way. I think it's pure coincidence that you kicked at that point.

Having said that, I don't see how this crash could have occurred. FMLOutboundHandler$OutboundTarget$7.validateArgs complains that the passed argument isn't a TargetPoint, but that's exactly what we pass in NetworkHandler.sendToAllAround.

Does this happen reproducibly, or was it a one-off?

Sorry for the late respone, it only was a one-off and I am unable to reproduce it. So if you want you can close this issue.

OK closing. Feel free to reopen if it reoccurs.
