I have a funny story. A couple days ago I was crafting an Ark tool. I don't remember which one, maybe terramaster 3 or 6 or Key 5 or 9 or probably just burning low MU materials on L fap BPs). Anyway, I finally got to see another Golden Key BP in loot. It was only 1 click, so was a nice surprise, but not really remarkable enough to remember which tool I was crafting or even to register a global, if I recall right. I offered it to Svena (100 ped per click sounds good) but she already has plenty of clicks so didn't want any more. So tonight I want to go hunt but I've got too many items in my inventory to run fast. I start one of my least favorite jobs of sorting the new BPs into their proper BP books and deciding what to do with duplicates. I come to the golden key bp (which I'd forgotten about by now) and drag it onto the Ark limited book, only for some reason the book seems to be malfunctioning; it won't take the BP. I try dragging a couple more times without luck. Weird... it says this BP doesn't belong in this book. So I right click on the BP to see which book it's supposed to go in, and it says "Arkadia Tools". Hm, odd again, I think, that they would include a limited BP in the Tools book. After dragging it into Tools, now I'm curious which slot it went into. After staring at it for about a minute, it slowly begins to dawn on me that there is no "L" in this blueprint's name.... So all I can say is WOW, I never expected to get the UL golden key BP! And my key BP collection is complete! Keys 1-10 and Golden Key UL BP. I didn't loot all of them, but it was really nice to loot the one I would never have bought You can be sure I'll be checking it again in the morning just to see if it's still UL.
