I don't know why the log only tell something about that mod,but the conflict happen only when enable this mod with that one.

Weird. That I don't have any heating towers. I think this is someone elses mod causing a problem, as its prototype is indexing a nil value. Are you sure their mod works properly without mine?

Actually, they work.When add Corrundum to the mod list,above report are showed.
I will try Corrundum 1.0.2.

- On prototypes of entities with circuit connector removed circuit_wire_connection_points and circuit_connector_sprites but added circuit_connector.

A vanilla changelog Version: 2.0.7 Date: 20. 10. 2024 introduce this change,and I saw the outdated version of code at that mod.
Ridiculously,I enable it and it run,even at the mine destoy platform version release to these day.

I don't get. I feel dense.

In my opinion,there are some outdated code at that mod,ElectricHeatingTower,and some code in Corrundum let the game take action to that outdated code.
It means that it isn't your mod's problem,and you don't need to do something to solve it.
I already make a report at that mod.
