I know most people run dungeons just running through the optimal path, especially while playing with other players in roulettes to not "waste their time" and so on.

However, I decided to run it today on my own pacing, and just to check out if the optional gobbos still award chests, and to my surprise they do. But the chests always spawn on top of them, making it very frustrating to click on the chest to open it.



It's very small and probaly not relevant for most players, but I think it's an easy fix. Just need to make the chest not spawn on top of the goblin you just saved.
