I doubt it's a common bug since there's no report of it till now however there's people who reported similar thing happening before so I doubt it's a new glitch. as for the problem I heard it's usually because lack of space during update, which is the reason I discovered this bug cuz when updating there's warning not enough space from Google.. Someone said to free some space and re-install the game so try that first.

finally try filling this form

https://form.fate-go.jp/formmail/fms/4e34d7279

it's an inquiry form not recovery account form. the first collumn is your real name, 2nd collumn e-mail address, 3rd collumn your device type, 4th collumn your FGO ID, 5th in game name, then gender and in game birthday. last form are filled with this :

メンテナンスと更新の後、一部のサーバントが2番目のアーカイブにありません.

which pretty much means "after maintenance and update, some servant are missing from 2nd archive."

good luck
