Before last night, I had 2 Medals (Medical Facility). Tonight, I have 8 (3 on MF, 2 on SBE and 3 on Rumble in the Jungle). It's not like I can get all 24 thanks to this glitch, only 6 of them. It's because those 2 rooms are unique to all the other Combat Challenge rooms. It's a rather simple glitch, but a very time consuming one.
Because of Medical Facility, I never tried the other rooms.
