This issue has been posted to the bug report many times but because people do not corroborate the reports on time it gets lost and nothing is changed about the situation. In gridded zoos (or zoo areas) guests get stuck walking in circles. They eventually form giant baitballs with hundreds of guests and staff inside the baitball. You remove the guests group by group from the bait ball move away from the area for a minute and the bait ball has reformed at the exact same spot with new guests. It's making playing gridded zoos pretty much impossible which seriously hampers gameplay for me as I love building gridded. The latest issue tracker link is posted below. If you notice this issue, please respond so it can be fixed.
