Invisible Monsters

in maps " i currently do not have one so its hard to remember the correct name" but maps with those fragment invisible flower stuff? i run it opened a breach and spawnd the boss in it and the boss was completly invisible this whirlwind dude i can damage the boss but i cant see him. same for some mobs. i opend 2 of thos in the keepers of the flame league both times some monsters are invisible, especialy the boss, what is somewhat scary. im not sure if this is correct but maybe you check it out. thanks GGG

They're invisible because the game is constantly re-loading shaders in the wrong way. If you press F1 you'll see your Shader bar is most likely green and completely full all the time. Last patch this problem didn't exist, they need to fix this asap.
