Not 100% on the version being pre-release, but I did just get the update from yesterday. I crafted the pick and shovel on the wyvern level in preparation for the staff and after about 60 seconds of play time with the pick in my hand, the game crashed with the attached crash report and a message saying I have an unsupported version of the game installed. The NPE in the crash report was referencing the draconic tools so I'm assuming it has something to do with that. Please let me know if I can help in any way resolve the issue. I'm playing with FTB Revelation pack installed.
