I've almost completed the "decoding ancient ruins" mission for the second time however it's damn near impossible as I think it's now bugged. All the known obelisks I have tried and tested previously for Culture 7 using one Totem "To" to scan have given me nothing. The pictogram now calls for what looks like two Orbs but when I use that combo it gives me the incorrect combo message. So frustrating!
Planets I have tried and failed scanning for Culture 7 scan are:

COL 173 SECTOR KY-Q D5-47, 9D, -10.8195, -89.8905 OBELISK R08
SYNUEFE ZL-J D10-109, E3, -26.653, -148.425, OBELISK K26
HIP 39768, A14F, 7.0924, 170.2272, OBELSIK P27
