Animals jump through barrier

[Garywayuk]

I'm having numerous issues with animals escaping.

I had an orangutan enclosure with a glass barrier at 6m. The animal jumped through it and escaped.

I extended it to 10m. The same thing happened.

I replaced it with electric followed by concrete. The same thing happened both times.

Does anyone know why this is happening? I've also had it with a few other animals.

I had this happening with my ostriches at one point and it drove me up the wall. Checking traversible terrain gave no indication what was wrong, the barrier was at 99% but every time the ostrich was put back, into the enclosure, it ran straight towards one corner of the enclosure and turned up on the path between the guests out of the blue.
again checking traversable terrain gave me the 'escape over fence' icon right ther in between the guests.

In the end I noticed, that there was a tiny maybe 2cm gap at the bottom of the fence, where it was not quite on the terrain and that was the corner, where animals escaped. Took me forever to get rid of it. in the end I got it fixed aber many struggles and the issue was possibly that I had built the barrier too close to the path. Not sure though. Best way to fix is to mark the area of the barrier where the animal escapes and gently push it away from the path. It seems to re-calculate where the ground is and then it closes completely. No more escaping ostriches for me now.

I had a Hippo pass a 3 meter wall once.
Finally i figured out what was wrong.
I placed a Plant Screen enrichment too close to said wall, and when the Hippo went throught it, it would have been stuck in the
wall.
So it unstucked itself and while doing so glitched though the wall.

Placing toys too close at a wall can cause issues (it didn't knew how it works, it was clearly a missplacement from my side).

Didn't got climbers/jumpers until now... i place my red pandas and some lemurs now, this threads leaves me
slightly concerned
