The temperature of additional material placed on the conveyor loader is not calculated correctly.

We are building a mechanism to generate electricity from the temperature of the regolith using a conveyor.
At some point we found a situation where the temperature of the material placed on the conveyor loader is incorrect.
As you can see in the image, the temperature is not calculated correctly. (The temperature returns to the temperature before loading.)

This situation may not occur (calculated correctly).
My own feeling is that it occurs 70-90% of the time.

I'm attaching the saved data which is definite that it happens in my environment after a few attempts.
We have installed a large number of mods, but we have confirmed the occurrence during the trial even in a completely vanilla state with all mods removed.

Japanese text before translation is also attached for your reference.
