this happened to one of my friends as well.. lost almost all of his crafting skills that he had lvled on a new acct.. poor file saves before end of last wave id assume .. and yah beta testing but still why grind for days just to lose it to bugs.. better not to test at these rates. honestly it will take at least 25% of the expected up time to gain what is lost (and thats assuming you have others to help with the things u need to supplement *i.e. blacksmith to aid carpenter*) and even then its gonna wipe soon so makes u question if its worthwhile.. i see im not the only one who feels this way.
i very much wanted to test and be a part, but it's just hard to justify... dont fail me on the final release
