Question Junimo letter

On the sixth day of summer, and picking the joja warehouse path, I received a letter from the junimos saying “please come to the community center…” I went twice once in the morning and once after 8pm. Nothing happened, I went the next day because I do have a mod that gives my farmer a birthday and it happened to be the same day so I thought maybe that was the problem but it still didn’t work.
Is this a glitch or…….
