I just sent out requests for mystic maps but got the message that two of my neighbours didn't get the request as I'd already asked them for something. This was news to me, as I haven't requested anything for at least 2 days! I had just agreed to SEND maps to 2 neighbours, but can't see why that should stop me from asking for maps in return. Any ideas why I got this message (I only have 18 neighbours so it wasn't the number of requests I was making)?
