The first Kanathar ending seems to be bugged in both 0.7.4 and 0.7.5 (bought it on Gumroad to check). I've gone through the monolith then went back to Kanathar to try to proc it, I've even gone as far as possible through Cray's path without hitting an ending before going back to Kanathar. Nothing. And since my character never tells him anything, I can't get that ending or any of the following endings, locking me out of four achievements. Hope this can be fixed soon, really enjoying the game!
