I found these mistakes when playing:

1. The game is pasma after playing it 2 or 3 hours, it stays frozen the time and you can not do any action, the game does not close only remains frozen.
2. When starting a new game (you must have played before a game of this game) and start taking actions with the idols you can notice that there are status messages from the idols of the previous game.
3. When you release some songs and press quickly to jump the messages of the progress states and the stars, you can see that progressively the place where the messages appear are phased out.
4. When continuing a game, assign work places again, it can be only one part or the whole template.

I encounter a bug when playing :

When you create a new game, sometimes you get events concerning idols from a previous game, you can also have buisness proposal for idols from a previous game

the "auto" is deactivated while you play.

whenever a disc is released, when I schedule a vote, all the idols fall into depression (mental 0) and when the concert is activated all arrive at -30 or -100 mental health.

One of the things I've had happen over the past few days is that sometimes if I drag an idol to the stylist, I can't drag anything anywhere else (singles, concerts, other idols) I drag it there but nothing happens. 
Also is there a limit on how many staffers can be on auto-practice/styling? Originally I had stylist/choreo/vocal on auto. I added another stylist and even when auto styling was selected, it won't work.  It works if I drag an idol to the stylist tho. 

Edit:Can we get a warning telling us our election isn't ready if we try to start to attached concert without putting it through production/ logistics? I forgot to do it and then was unable to do so after the concert had already happened. I cancelled it lol

I noticed that after the 2nd floor, I am unable to drag any idols or singles to staffers in those areas (even after quit and restart).

I think for negotiations, even if you get a 0%, it still changes the amount paid, sometimes more sometimes less. Is this intentional?

Pushes are empty upon restart of the game also

After changing policies for the first times, most of them won't change again. They do appear highlighted in the droplist but the change isn't reflected at the root. 

Ex : i first changed idol salarie on "low" and later came back to make it "satisfied" but the change wouldn't work how many time i tried andit was the same for most of the options.

There is weird bug with media/shows
If I make multiple shows (doesn't matter if simultaneously or one after another), it always overwrites the casts of the other shows.
So for example, when the bug first appeared, two of my girls had three shows instead of one.

I have to try a bit more, but the solution for me seems to save and load after each show. While it doesn't fix the old shows, the new shows cast will be correct.

Proposal seems to be stuck for me, changed it only once since starting the game but havnt been able to change it for a long time, at least two months have passed since last change. 

Edit: scratch that, none of my policies are changin. I can pick a different policy in the dropdown menu but they dont change.

Not sure if this is a bug or not, but at certain point all of my idols suddenly became depressed, at 0 mental stamina, or around that number (1-5) for no reason, concerts were going well, nobody complained, we had one girl who was caught with a boy but nothing happened, just some buzz, I tried to quickly recover and hired more new talents but they also got dropped to 0 mental stamina one or two days later. So either something serious went down and no one told me, or its kinda bugged out.

Just a few things I've encountered while playing the game, feel free to ignore if you've already been notified of this:

1. Game freezes up after picking up an avatar from time to time - requires restart
1.5 After cancelling a job, there is a chance that you can't drag in a new job
2. Character in two places - usually because auto and manual action are performed at the same time
3. While during hiatus, I can still perform Activities/Contracts - don't know if intentional
4. Auto styling turns off every reload

Japanese characters are not displayed correctly after game reload.

My group name contains japanese characters and it was displayed correctly, but after closing the game and opening it again I get '?' in place of japanese characters in dialogs.

"Release" button for releasing a single is disabled when it has to be active.

One of the idols was on hiatus and I canceled her hiatus to release a single. But "Release" button was disabled until I pressed "Formation" and without changing anything in the formation pressed "Continue". In the screenshot you can see that all the songs use the same formation but some can't be released until I press "Formation" and "Continue".

I had the game just stop at the audition background the first time I tried a regional (middle) audition. Had to close the game window and then start it up again on the autosave to be able to proceed. Sent you a bug report via e-mail, just in case.
