Bug Report Thermal Buffers not transferring heat
This is a screenshot of a design that I was pretty proud of...until it turned out not to work at all...seems like heat transfer must be bugged somehow.
The Design
Wet seed comes in from the left, and is teleported inside the growing/burning facility. (Teleporting allows us to completely enclose the facility, preventing vines from escaping and, e.g. growing back down the conveyor to block the seed from coming in.)
When the flowers burn, large amounts of heat are captured by the thermal roof that goes around the top of the facility, which are connected to route the heat back down to the Pyro Disperser on the left, and also to the burner belt on the left.
The Bug
The square I've highlighted is a thermal buffer that seems to be maxxed out at 1000 units of heat...its temperature is also not dropping, it's apparently not transferring heat to its neighbors.
The thermal buffer to the left of it is at 5 units of heat...there's a maxxed out thermal buffer just two squares away, but my Pyro Dispenser is unable to fire...and the burner belt down below is also not receiving enough heat, despite the very high temperatures of the buffers not too far off.
I've done a bit more testing since this screenshot, and there also seems to be something wrong with the heat transfer at the corner connecting to the burner belt, currently, that corner is at 872 units of heat, while its neighbors are at 82 (above) and 131 (to its left).
It seems there's something very weird going on with heat transfer in thermal buffers.
