it may sound strange but... I noticed it going from 95->96 (but forgot about it for a while)

when I stand away from the roof and the player stands away from it it looks normally

when I stand under the roof and the player stands under the roof it is ok

Player is still in the same spot but I moved away from under the roof, the player is not visible for me

In this situation it isn`t annoying but I have this problem in many places
(the speech is normally visible)

where could be the bug?
