Maybe some people have increased refunds due to escaped animals, but that's definitely not my case. I have not escaped animals warnings. My refunds are just based on the unhappiness of guests because they wish they had stayed longer to see X animal. And it's not related to the trade centre because I have tried getting it empty, no animals now, but they keep saying the same and the refunds (in the Unhappiness category) are above 100k per year
