In the ROBLOX game "Cell to Singularity Evolution Island" the dinosaurs you buy can't move. They are probably supposed to move but they just stay in the same spot. When buying a creature multiple of them spawns on your island, one by one. All of them spawn at the same location and can't move meaning they overlap which can look pretty weird.
I did not know what tag to select so I selected "Beta" since the name of the game says "Beta".
