1. "Play Button Crash" - By far the most destructive problem encountered by players. This bug or whatever it is appears quite randomly, to players that have not done anything out of the ordinary. It causes players to crash out of the game when they press the Play button, making it impossible to play the game. The only way to "fix" this problem known currently is to delete your saved game in the options menu. Purchased Toxins may be reimbursed by contacting Capcom Mobile at their website.
THIS PROBLEM OCCURS MOST OFTEN WHEN A ZOMBIE SENDS FOOD TO A FRIDGE, BUT IT IS CLOSED OFF, AS IF A TABLE OR CHAIR IS BLOCKING IT. Try to leave your fridge as accessible as possible!
2. "Friends Not Showing" - This problem happens when you have too many Zombie Cafe friends. When you go to the map, not all of your friends will show on the map, hence making delivery difficult. The map will occasionally load more people if you scroll over to the left. But still, not everyone shows up most of the time.
This can be solved simply by clicking friends under homepage of zombie cafe, then uncheck mark names so that they will not show in the game. You can checkmark the names of those that you want to visit.By uncheckmarking the friends, you can checkmark them anytime, and they will reappear in the game.
3. "Wrong Friend Cafe" - When loading into the cafe of a certain friend, you may occasionally find that you are in another friend's cafe who was not the person you selected from the map. This may occur on only certain cafes while others function as they would normally. This problem impedes the delivery of cooked items.
No known solution, but does not harm overall game.
4. "Zombies Go Brain-dead" - Zombies that have been assigned jobs may stop working and just stand still upon loading the game. This is not just the occasional "day dreaming" that the game describes, but a problem that causes food to be unattended and rest to be roused. Your affected zombies will walk into your cafe, no matter where they were before and stand at the entrance doing nothing. The zombie will have no task registered on their task board and will stand still until you assign them a new job. Users have speculated that this problem is more prominent if you have other push services, such as alarm clock, msgs, other games etc.
No known solution.
5. "BRAAAINS!?" - This is a problem that concerns the appearance and the occasional disappearance of the games push notifications. Sometimes when you receive a notification that a food item is finished cooking, you may find that upon entering the game that your food is in fact not cooked, and may even register the exact same time as the last time you were in game. Another problem that I have personally encountered, is that the notifications don't even show up at all, which have cause me several burnt dishes.
No known solution.
6. My cafe is green, what should I do?
This is not a glitch. Your cafe is green because you have changed your time. Always make sure that your time is set to automatic under options. After you have done this, it will take some days before your cafe changes back into original color.
7. Friends not appearing on friend button under zombie cafe home screen.
This problem is that you have over 64 friends (which is the current maximum of allowable friends), OR the friend deleted you from facebook/game center. If you have under 64 friends, and the friend that isn't showing is still your facebook friend, then what you have to do is delete a single random friend on facebook that plays zombie cafe. Then, your list of friends will come back.
8. Zombie not gaining health fast enough.
This is not a glitch. Apparently, if you leave your game on, the zombies will recover faster than if you close your game.
9. Zombies and humans can walk through objects if placed at the right time.
No need to worry about this.
10. Rarely, some pictures of dead bodies or human are frozen and does not disappear. Simply click map, then click back to your cafe and the problem is fixed.
