I have a line with some overcrowded stations. Empty trains going to the passengers destination stops there, but passengers won't get on. As soon as I solve the overcrowding problem by adding some more capacity to the station (new platform tiles, extension bindings, etc.), the trains start to load passengers again. I remember that only overcrowded factories won't accept new goods, but this shouldn't affect passengers stations, am I wrong?
I found the same problem both on the stabe 102 and on the last nightly (using the same savegame), windows version, pak 64.
