Placing a tree causes the game to crash.

Error while running event CW-tesseract::on_built_entity (ID 6)
CW-tesseract/control.lua:347: attempt to index field '?' (a nil value)
stack traceback:
CW-tesseract/control.lua:347: in function 'calc_energy_consumption'
CW-tesseract/control.lua:486: in function <CW-tesseract/control.lua:414>

I think this is due to the fact that the built belongs to a force that does not contains tesseract data

You're right I didn't expect a player building trees please test the new version I just uploaded

Thanks, it working well
