I have the same issue. Didn't notice until the energy cost changed.
Ok, that explains why the first quest had five paths.
Hey!Are any of you running into this issue further?
Quick update on this: We DID push a fix for this and you shouldn't be able to enter the next chapter without completing the prior. If you are CURRENTLY in that quest you'll still be able to go through with it, but one you're out of it: it will lock.
