Still no Fast Forward
It seems like when they immediately get to Gaborone (airport hub of Botswana), they're signing up for charter flights to a national reserve... however, the teams are equalized since in Joey & Meghan's flight scene, you can see Max & Katie and Caroline & Jennifer behind them. In Mona & Beth's charter scene, you can also see Chuck's mullet.
In cap 24, Bates & Anthony are showing off a Detour clue running with tribal people with bows & arrows. Surely one of the Detour choices?
In Joey's scorpion scene, it's definitely a Roadblock as you can see him holding the red clue while reading the instructions. Scorpion holding and consuming prior to hunting them?
The hilarious tribals in the cargo might be the route info task after landing at the tribal reserve's nearest airfield. This is what I think:After teams arrive at the tribal reserve, they have to take 3 or 4 tribal people back to their camp via Ford Escape. When arriving at the camp with the tribesmen, they will get their next clue by one of them revealing a Detour or Roadblock clue.
Of course, this is purely speculation. Exact location is unknown, but it is at a sandy-ish and open area with dry grassland and minimal vegetation.
