I have done extensive testing of this bug in my large zoo, not sure it is just one thing, think it is actually a few different things;
- Old bug is still there with primates, who always had an issue with false escapes during climbing, this is far worse for baby animals, since i have removed all my baby primate I am not longer getting adults escaping whilst climbing
- Animal pathing has changed, which means that some animal will find escape routes for previously working habitats - I had a few of these where animal were finding little gaps and nooks outside the barriers (I use a lot of natural terrain and null barriers) I managed to fix all these to stop the escapes
- NEW BUG - random animals being marked as escaped whilst just standing around. Again I found this mainly with happened with babies but also some adults. Wide range of animals, adult lions, zebras, camels. Animals are marked as escaped despite being in middle of enclosure, sometimes they are then instant boxed, sometimes not.
I have managed through remove a high number of baby animals (all my primate juveniles are now in storage plus 40% of all other animal babies) and fixing habitats to get my zoo back on track. At one point my yearly loss hit 200k before I got it sorted. Took me about 5 years, lost about 500k in total. Now I am only getting the occasional random escape, possible 1 per year.
Good news is they fixed the bug which effected primate social when climbing, small bonus I suppose.
Two steps forward one step back again with this patch. The bug with exhibits needed to be re positioned before you can call a keepers has been added too.
You will also find that your economy is getting hit from two sides, the refunds but also your ticket revenue will drop. My guests went from 8500 to 6000 due to escapes, took several years to get it back up, hitting ticket sales.
