Video summary
Press to jump
- 0:00Duncan, Harry and Osie take their vehicle to an abandoned yacht to collect resources.
- 1:03Shotgun-wielding Finforcers interrupt the loot run, sending the crew back to their respawn point.
- 10:00Back at base, overflowing cobblestone blocks a system and the crew investigates its damaged armour.
- 12:20Harry experiments with soul soil, lava and ice to automate basalt production.
- 17:50The crew returns to a deep underwater hole to put Duncan's newly crafted diving helmet to the test.
The loot is there for the taking. Unfortunately, so are the shotgun-wielding Finforcers, and Duncan, Harry and Osie's yacht expedition becomes a repeated journey between dropped belongings and the respawn screen.
"Power Core Problems | Jaffa Factory: Mad Jeff #55" is the week's most-watched new upload, with about 30,000 views. The custom Minecraft modpack and adventure map, created by Harry and Nick, gives the crew an uncomfortable reminder that impressive equipment does not guarantee an easy outing. Back at their industrial base, broken armour plates offer one explanation for the punishment. An overflowing cobblestone system needs clearing, too: even after escaping the yacht, there is maintenance waiting at home.
The comments have their own practical concerns. One viewer proposes making biodiesel for the vehicles; another asks whether Create could support a trailer. The transport fleet is becoming a project in itself.
Duncan posted three videos across the week. "Into the Deep | Jaffa Factory: Mad Jeff #56" takes the gang beneath the oasis and is currently drawing the most daily views of his uploads. "Antigravity Metals | Jaffa Factory: Backrooms #53" returns to the hunt for increasingly demanding materials for the remaining eyes.
Subscriber numbers were unchanged across the week, while daily viewing is running at less than half Duncan's usual pace. Nearby Minecraft channels are also seeing softer daily viewing, including xisumavoid and BionicLMAO, though fWhip and al1 accumulated much larger weekly audiences. For Duncan, the new Mad Jeff episodes remain the busiest part of the channel, with "The Problem Solver | Jaffa Factory: Mad Jeff #54" also continuing to draw viewers.

What viewers say
With these vehicles they already have and the ones they're planning I sure hope they'll do some biodiesel glorp soon. Just dig out a basement, grow some potatoes for ethanol, and seeds for seed oil, combine them and hello! No more fuel crisis
