Tamriel Rebuilt's large gates are broken with object paging active grid enabled
This happens in Firewatch, to move to it:
coc "firewatch"
A TR's large gate original behavior is it opens once the gate is activated, the sound is played too, and to close it get to where the gate is at (when opened) and activate it again, or leave it open and it will close on it's own once you move a bit far away from it.
When object paging active grid is enabled the large gate actually opens when activated (the collision box moves to where it's supposed to be when the gate is open) but it appears as if it wasn't opened (because the texture stays in place as if the gate is closed) and the sound is played, to actually close it you have to activate the gate's texture that stood in place not the collision box.
To fix this behavior leave the gate open so it can close on it's own (after you move far away from it) and then after that the gate will behave as normal, you have to do this for every large gate, every new session.
