I have a tranmission trait that depends on another two traits to be unlocked. It goes something like this:

Symptom 1 -> Symptom 2 -> Transmissions 1,2,3
Symptom 1 -> Symptom 3 -> Transmission 4

Transmission 1 & 2 -> Transmission 5
Transmission 3 & 4 -> Transmission 6

Transmission 5 & 6 -> Transmission 7

Every other conditional unlock works except for the unlock condition for transmission 7. It just remains locked, despite being set with the right unlocks, as a non-starting trait, Is there anything I could do to make it work?
