I mine with my fairly fast and competent mining equipment (I'm looking at you bedrock pickaxe and OP hammer) and I get kicked for "Internal Server Error." What does this mean?
It means that an error occurred on the server that did not crash the server. Someone would have to look at console or the logs to identify the real cause.
it has to do with breaking blocks - any blocks - and it makes mining a cast iron *****. There are times when you crash more than you mine It's something caused by the last modpack update, never happened before that - now, its very frequent.
It has to do with either hyperenergetic nitor, leggings of the burning mantle, or any other item that makes phantom light sources being active while mining. It is a Cauldrom (MCPC+) specific issue that I have been trying to get to the root of for some time. I finally got the part of the server log I need to take it up with the cauldron people, will report back when I have more information. reference: http://skcraft.com/threads/need-crash-log-for-thaumic-tinker.3300/
