I've tried re-entering the room around 20-30 times and still no luck.
I've noticed one more thing - this bug only appears if you previously opened that blue door. That happened to me on both doors - in the Mansion and in the Ice Hell (sorry if I didn't name them correctly
). So, on my first time in Ice Hell I've found blue key, opened the door, but I didn't have silver key, so I've left the location. Next time (that means now ) I have the key, but I can't find blue keycard on the same location. Same problem in the Scientist's Mansion - Blue door, no key.Hope that helps a little
Sorry if I said something wrong, 'cause English is not my native language
