Wrong temperature calculation on Conveyor rail

Debris exchanges heat with the tile it is currently in, and for if the tile it is currently in is not vacuum, and the tile below the debris is solid it also exchanges some of the heat with the tile bellow, currently this is the case even while the debris is on a solid conveyor rail, until that changes you can avoid this issue by having the conduit rail avoid going through the tile above the joint plate, as what you are noticing is the debris exchanging heat with the joint plate bellow.

Changed Status to Known Issue

Thanks. I will make that modification for now until the update

“Until”? 😱

I also shudder at the thought that debris (on conveyor rails) exchanging heat with the tile that's below it (currently accepted as normal behavior, in my experience) has been thrown into "known issue" territory. I surmise high potential for builds breaking if this changes.

Technically it's a bug and not an exploit at all. Any update will always break some previous build. This xkcd comes to mind: https://xkcd.com/1172/. What would make more sense is that the debris exchange temperature with the tile it's currently in first and that tile exchange heat with surrounding tiles (or to a temp shift plate, a bridge in that tile, a large signal distributor, or ice maker). The fact that it is in a vacuum shouldn't change that basic fact
