Found another bug on Hikaru's route i think. On june 5th (thursday) you can do the kindergarten job and the next day (which is actually friday when the job is supposed to be available.) June 6th which is Friday you can do the job as well.
Hmm... I couldn't really see how this is possible (checked the code and it shouldn't happen). Can you tell me if you encounter it again? (with SS if possible)
