All plants reverted back to level 1!
Suddenly all my plants have been reverted back to level 1! When I go to the almanac, they are shown as upgradable, but the info screen is blank and laggy. In arena plant selection screen there is an "upgrade to mastery" button, but it does nothing except say "level up, ***** reached level 1!".
What is going on?!
Have you tried to force-close the app and reopen it?
