Version: 1.0.1 What is the bug: One of my players was using his Osmotic Enchanter, and didn't have enough Vis in his Thaumium-bossed Silverwood Wand. The server crashed, and I could not start the server again, as it would continue to crash for the same reason. Mod & Version: Thaumic Tinkerer 2.5-1.7.10-162 Paste.feed-the-beast.com log: http://paste.feed-the-beast.com/view/23fce3ab Can it be repeated: Did not attempt to repeat. Known Fix: I fixed it by destroying the Osmotic Enchanter in McEdit using the coordinates provided in the error log. This assumes that a user knows how to repair a corrupted world using McEdit.
