I too had forgotten how to navigate the Residue Processing conveyor belts and kept going in circles.
The conveyor with the mines needs to be a bit more obvious that it’s the right way, because when I see it mined, it just make me go “nope, not going there”.
Same for the melted vent cover at the beginning, I didn’t even see it till I had cleared the area and went downstairs to the locked doors.
Especially since I got distracted with the headcrabs appearing and guard running into the barnacle.
It really needs to be made more obvious, like it getting melted with bright lights from the flames, dynamic shadows, dripping red hot metal, appropriate sounds, etc.
