I've never gotten an Ancient SOS in the past and have been trying for them the past couple of weeks. I've gotten 66 MIB's this quest without any being an Ancient one. 0/66 is certainly not the documented 'about 1/25. Are Ancient SOS's turned off while the booster is being worked on or is there a certain situation in which you need to open the bottle? Perhaps hicupping stone drunk at a moongate with both moons full overhead?
