TIL wearing Thermal Pads while delivering chilled cargo damages it

I tried doing Order 375 (from Evo-Devo Biologist to Mountain City, chilled cargo) many times, even building extra ziplines to make the shortest route possible and always my cargo took too much damage. In exhasperation I took off my thermal pads and did on the first go *face palm*

I mean, it does make sense, but I never expected the pads to affect anything other than Sam. I'm both livid and impressed.
