The vents that generate in the world outside of the starting area are a different size than the generator restricting placement of the generators to the single vent in the starting area that is the correct size. The vents outside of the starting area should have their x and y dimension's increase by 1 each.

Thank you will correct in the next version

- Fixed a bug due to which it was not possible to install the generator anywhere except the start area.

Attention! Version 0.0.6 is different. If you have installed the mod version> = 0.0.5, then delete it and after that load your save, this will remove non-compatible geothermal sources. After that, save and install version 0.0.6. If nothing is done, in this case, a new resource will appear in the starting area and you will need to rearrange the generator. New compatible resources will appear on the map, the main thing is that you do not confuse them with incompatible ones.

Increasing the size did not give anything, even if it was increased 10 times. I had to reduce the generator, but then the resource at the start zone was not compatible. Problem solved but version 0.0.6 is incompatible with earlier versions.
