Upon re-logging into the game all water troughs will be empty
+
When loading from [[Mobile Saves|Mobile-specific Save]] files (both Emergency Saves and Backup Saves), all water troughs are always empty. Therefore, [[Slime Ball]]s will never spawn the following morning. To reliably produce Slime Balls on mobile versions of the game, it is best to fill water troughs at the end of the day, shortly before going to sleep.
