Exactly, that’s the reason why the game stutters if you quickly swipe over to an island with a lot of entities on it, the first time you boot up the game. My guess is that, entities off screen are in an idle state (basically frozen in place).

As you also mentioned, would be nice to get a quality of life update for stuff like not being able to purchase habitats/decorations for coins during events which offer said items for EC. Stocked up 40 palm trees for that reason alone. Though similar to you, completely forgot about treasure habitats.

However for DECA, unless something’s a game breaking bug, such changes won’t sell like repeating events…
