I’m currently in stage three of the game, and my workers will temporarily simply stop working. It will last anywhere from 3 to 20 seconds and will happen anywhere in the development, although most commonly a bit before the end of a part of development (like going from gameplay to stories and quests). I have a screen shot of it (also, please don’t judge my naming of things):
this wasn’t a time when no one happened to be making bubbles, it was a span of about 20 seconds. Also, this isn’t like many others, where workers will stop working altogether, this is, again, temporary.
Is it only the bubbles or do you have a complete screen freeze?
Only the bubbles.
It’s really hard to point out what’s causing it.
I suggest sending an email to support@greenheartgames.com which contains your problem and also your system specs.
I wasn’t terribly concerned about it, I was reporting a bug to let the Devs know.
I have same bug D:
Always in final office and only with AAA and large games.
Maybe their bubble blower is empty…

I got an entirely new perspective on life. Well, mainly Game Dev Tycoon, but still.
I know what the issue is! BATMAN!
It also happened to me. Try closing the game. Relaunch it then try your luck on loading the autosave file 
They probably ran out of ideas about puppies at that point and all had ‘writers block’! 
Don’t judge my naming style.
Learn to take a joke?
I wasn’t actually mad at all, it was a joke as well.
Jokes here end with a smile or something 
Oh. I’m smart
or 
a puppy
I get this “bug” occasionally. I solve it by saving the game then exit to desktop, then boot game back up. Works everytimes, even late on in the game when your players bubbles might lag.
