not sure why it doesn't work or how to reproduce this bug, but I am sure it happen when off screen, see in the picture, it should never reach above 20, only this particular liquid pipe thermo sensor that doesn't work when off screen, the position is far right of the map, liquid tank in the steam turbine room.
mods I use: zoom out, pliers, POI destruct, geyser calculation.
before I decided to post this, it had froze my coolant and broken my aquatuner, forced me to reload, coolant was polluted water back then, right now I switched to super coolant and keep checking it every once in a while.
Steps to Reproduce
going off screen
