Yeah, I had this thought last night while completing. Bouncing around the map to search for these things is not fun. I wasn’t using the difficulty reset because that feels like an exploit.
IMO, explore needs a new interface in general. Should let you switch kingdoms on the fly (via dropdown or something) and put an end to kicking back to world map.
The explore memory leak (consistent slowdown/stuttering after ~10 explore battles) isn’t helping things with this event, either.
