badgeos_revoke_achievement_from_user using old user meta methods

[uncannyken]

It seems there is a bug in BadgeOS function:
badgeos_update_user_achievements()
which is called in:
badgeos_revoke_achievement_from_user()
It seems you are using user meta for saving achievements but in newer versions of the plugin you are using your own tables. In the functions above there's no support for the newer versions.

BadgeOS Version: 3.6
WordPress version: 5.4.2
