I totally agree with Evolution. Since the free update 1.3 the game has almost become unplayable. It's impossible to play for a minute straight without being notified of a staff member not being able to reach an empty and properly connected staff room, or a hungry animal that turned out to be hungry because the keeper refused to use the keeper hut he had been using for 100 in-game years.
Based on my personal experience in my current zoo and on many comments in this post, it's striking how as time went on the game got worse. I mean, DLCs and free updates are mind-blowing and I truly enjoy them, they are great and the additions of the Australia pack (both animals and pieces) are awesome. But, some months ago, with much fewer content, I could easily play peacefully for hours. Now that's impossible unless I play with the game paused, which I do not like at all since I enjoy much more to play with the game running.
It's very sad and frustrating since I really want to play. But the amount of extremelly annoying issues makes it impossible...
