Terrarium stays active while unloaded

The terrarium will not deactivate automatically when a day transition occurs while it is unloaded/offscreen, therefore it will spawn again the next night. This is getting abused more often on public servers so I thought I'd bring this up. I also suggest adding a global icon the terrarium while it is active, so other players can find it and choose to deactivate it if they don't want to deal with the Twins spawning for example.
