No Meaningless path in Event Quests
While playing "The Odd Couple" in Missing Dog quest, I found that there were 5 different routes, to complete. After completing 4 of them, I ended up in situation where 1 tile was left (98% completion), and nothing else to do in that path. I had to replay and loose half of my energy just to complete 1 useless tile.
For future quests, please do not add useless paths for the sake of exploration. If more paths are present for exploration, then add some rewards or enemies in each path, so its not useless.
To recreate the issue - In the "Odd Couple" scenario, 2nd half where paths split, just take 4 adjacent paths rather than straight one, and after 4 play-through, you will end up in similar situation as me.
