Collisions and physics works differently in different levels.

Hello, I am a junior developer and I create interesting door mechanisms. They can be closed and locked by placing a chair on the side where the door opens. But for some reason, my AI passes through doors in one world, while in another it works normally.
I tried copying all the elements from the main world, but it didn’t help.
I also tried creating a wall and adding a navigation link through it, and my AI easily passes through it.
The collision of the capsule on my AI character has the collision type “Vehicle,” and the grid has the collision type “Character.” Both are enabled. The character spawns identically on both maps.

Are you sure you don’t have different collision presets for each level, or the meshes therein?

Another possibility might be the omission of a collision box, an overlap setting, or an event (especially if the generate overlap events hasn’t been checked). See below:

I found a solution. Somehow AI change his collision responses on each level
