Monika won't show me the floating islands after restoring a backup

[FrostyyBR]

I recently reached 400 affection and got Monika to show me the floating islands, but then I had to restore a backup. I assumed that she'd show me the islands again in a greeting after I've launched the game a couple of times, but it's been a whole day and she still hasn't shown them to me.

I tried to see if I had already unlocked dialog box to ask her if she can show me them again but I haven't. The backup I restored was an auto backup made after my [rested] bonus, which had me at 401 affection. I currently have 441 affection and she still won't show me the islands regardless of how many times I say goodbye and relaunch the game.

Is there any way to fix this? Any help will be greatly appreciated!!

(Edit: Yes, the weather is clear and no, it's not winter.)
