Heat Doesn't Transfer Off-Screen

I don't doubt you're actually having an issue here. But what's with the green tinge on the POI tiles? Maybe i'm just seeing ****, if you're running modded, you should report the behaviour to the mod makers instead. Just saying.

If not then just ignore that - since you can reproduce this problem without mods running then you've got a genuine test branch bug.

There are a few aesthetic mods on there but nothing that affects materials or heat exchanges. This was happening before I went on the test branch and on unmodded games. I also found another thread with this issue.

I feel like it's a genuine bug because the system will work completely fine while on screen, but within a minute of looking elsewhere, the heat doesn't transfer. I get -50C Igneous rock, look somewhere at another project, look back 5 minutes later, and it's putting out 800C rock. I can literally watch the thermo sensor climb back up from where it was around 230C to 350+ when I move back onto the screen.

 

Try this w/o mods. Mods can have strange effects on anything else.
