I rode the ferris wheel on Friday with N(it was Spring) and today(Monday,Summer) I went to his castle and he was there and I challenged him.He had his Summer team...Is this any kind of glitch?Please answer....
No it's not a glitch.
It's because the Friday just gone was the 31st of January and today (Monday) is the 3rd of February.
"The seasons in Unova will change each month, going through the full cycle of spring, summer, autumn, and winter three times per year."
Hope I helped :)
