I feel for the ones who craft up their lineage, and want to go view it. But mistakenly click the end lineage button instead. Poof all their work is gone with no loot to show for it. I think it is a good feature to have just in case you build a lineage you cant handle, but I feel there needs to be a way to prevent unintentional selection.
And yes it is fair to say, learn to read, stop clicking things blindly, and even this is too much babysitting, and those are all valid (Hell I even thought of them all myself).
