Occlusion culling different in in-game Timeline

I have a problem with occlusion culling. I've set camera frustum to so that I get all the objects I want into view and baked occlusion culling - and everything seems right. In editor, when I select the camera and occlusion visualization, and in-game when camera is set occlusion seems right and in Timeline in editor the occlusion visualization is right, but when playing the Timeline in-game occlusion is cut way too early.

Does anyone have any ideas what would be the problem?

Here's the visuals of the problem:
