so you are right, some people were lucky enough to get 2 free LRs (LR20 excluded of course), my now every single player who plays the game and will ever play the game will get a single free LR whereas before only characters that existed when a certain update went live had a free LR. so some people get 2, countless more will get 1 where they would not have had 1 before. that is being generous and sure you missed out on a freebie, but i think it's quite unfair to get upset over that. what you can do is keep up with the lama dev tracker in the future so you can jump on any such situations if they occur again.
personally i still have several chars that need a LR to make the most of the new enhancement system, so they have lost out on a double free LR. but i don't care, because i don't need to do 2 LR's, just need to do 1 and get it right! incidentally lama land is very handy for messing with LRs because you can take a char from 1 to 28 in the test dojo and mess with all sorts of build choices. so feel free to make the most of that when lama comes back up!
