Just pushed an update Beta 1.1 that should fix these issues (if you're using the itch.io app, this is how you can update the game https://itch.io/t/49527/how-to-update-the-game ):

• Time doesn't progress at all on some macs
• Not being able to create singles after leveling up some marketing options to lvl 10
• A substory breaks if you don't have any "dance" staffers
• Getting stuck on the Nickname popup after clicking on a room with no staffer -> Nickname
• There was a way to launch a single with no idols

-----

There's also this issue that some players are having where the game won't load properly and instead shows the intro dialogue with the main menu background. This also caused their save file to be overwritten with a corrupted 2Kb file.

I fixed the 2kb issue, but if something happens and you can't load your game, please send me your save file at sadambober@gmail.com

Windows: C:\Users\*username*\AppData\LocalLow\Glitch Pitch\Idol Manager\data\auto_save.json
Mac: ~/Library/Application Support/Glitch Pitch/Idol Manager/data/auto_save.json

Your log file will help too:
Windows: C:\Users\*username*\AppData\LocalLow\Glitch Pitch\Idol Manager\output_log.txt
Mac: ~/Library/Logs/Unity/Player.log

You can also use F5 / F9 to manually save / load your game just in case
