I've been tracking an issue for a few hundred cycles where all the lumber loaded onto my conveyors comes out at 20C. (trees are all around 31-34C)
After further testing I've realized that lumber's temperature goes down when it's put into a container. It goes from the 31C it was harvested at down to around 23C.
When a sweeper moves the lumber from the compactor into a conveyor loader, its temp goes from 23C down to 20C.
