Well being as though shes been on my main street for 3 months now, i would think one ill effect would be IF i wanted her to move in if i really wanted her, i don't think i could get her until for whatever reason she left and her time came back up to move in. Since she isn't one i really care about its not an ill effect to me. I've had 3 move out and when molly moved in peck was in my campsite, i got him to move in and it took him 2 days to move in, i actually thought hes not going to move in. So with that being said i'm curious if dora was trying to move in with molly and couldn't because she would have been my 10th animal or if as it was said if she had to be asked to move in before she could. So there are lots of possibilities of what could have exactly happened to me with her. I am kind of curious since its a glitch if i could still end up with her being able to move in randomly or invited from someone else and still be on main street, that being said if she doesn't leave with peck when i finally kick him out.
