After using Apps corner calendar disappeared from start screen

[Jiiiveee]

Hello

I decided to try Apps corner yesterday on my Lumia 820 (WP 8.1 Update 1 without Cyan). I was able to start it fine but when I turned it off and it went back to start screen but my calendar tile was missing. All other apps had their tiles in usual positions but where calendar tile should have been there was only big empty space. I was even able to rearrange other tiles to the empty space where calendar had been.

Well I thought that okey I?ll repin the calendar tile to start screen. Calendar was still on my app list. But I was not able to pin calendar to start screen. That option ?pin to start? was greyed out so I was able to click it. So my phone still thinks that I have Calendar on start screen even if it is not.

Anyone had same issue and could help me? Thanks!

Same for me, but many more tiles disappeared and cannot be re-pinned. Very frustrating, I may reset my phone to factory settings.

Solution: Disappeared apps were moved into folders for some unknown reason...move them out and it seems all is well.
