We’ve had reports of a bug in Mercenaries Saga Chronicles – after learning the ‘Move Again’ skill a few characters can get stuck after opening a chest. We’ll publish a patch ASAP. Please avoid learning that skill (in MS1 particularly) until the patch is live.— CIRCLE Ent. (@CIRCLE_Ent) February 12, 2018
Good to know Circle is on top of this bug, as I've seen a decent amount of people mention it. When the patch goes live, we'll be sure to let you know.
