We just discovered a serious issue with all of the Hexo Singles standalone applications: Hex-n-Spell, Words and Suits Deluxe, Runaway Straights and Tumbling Dice
There is a bug in the app if you use the EXIT then SAVE GAME feature to return to the main menu without losing the current game. The saved game gets “stuck” and cannot be cleared. Please Note: any running game will automatically be saved if you exit the app. This save is working correctly the issue only occurs during a forced save.
See the full details and a temporary work around here
