All the other quest echo’s (other than boss/mini boss ones) that i’ve done (right side ones) had bonus stability along with them (im assuming because theres mobs to kill, so like normal echos it encourages spending more time in the echo and not just running to the end/objective).
As title says, the first quest echo in The Last Ruin timeline doesn’t have bonus stability with it, and im assuming this is a bug (and if not definitely seemed like it!)
