I was going to watch my recorded AATC but I didn’t see them they weren’t there. I think they must’ve got delayed or something. Also I wonder why other countries get to have episodes aired first!
Nick decided to remove them from their schedule at the last moment (something they've been guilt of doing in the past). They are erratic in that regard. Why they removed them? Spongebob probably, but who knows for certain. Other countries run on their own schedule though for many times throughout the series they've aired episodes first. Perhaps this just lines up with the fact that some countries premiered the series before the US as well.
