I recently had 3 tools change their name to unnamed and lose all data in the TiC tooltips. Upon placing them into a crafting grid, minecraft crashes. If any additional information is needed. I will be glad to give it to you. I should probably mention this happened after I messed with the config files generated after setting override module to true. I have since reverted that setting to false after I realized I had no idea what I was doing.

---- Minecraft Crash Report ----
// Surprise! Haha. Well, this is awkward.
