Red stain and abusing it by using configs

luka2211

So a few patches ago there was some kind of an engine update,which made regular stain not pass through walls. It still does pass through autohaven/macmillan/asylum walls even with the engine update that was made. Except that,people use certain UE lines and put them into their engine.ini file to remove mist/increase red stain size/remove all smoke/remove all particles(for e.g clowns gas) and etc.. Why has this been in the game since it was released? You devs should really do something about it.
