I don't know why but after update this game to 1.5.0x, two power plants plugins something crashes my game so I can't open the game. I check the plugin folder and found the "New Supply System" which was created (maybe) after updating the game. After updating, I try to add another plugins and makes two plugins crashes.
Those plugins are and in that folder names' plugins are:
- Geothermal Energy Power Plant -) Geothermal Power Plant
- Garbage Powerstation -) Waste-to-Energy Plant
After removing the old plugins, my city have no any electric source.

I tried to moved that folder contain to plugin directory, but... ugh...
Furthermore, I will post it...
I suspect its because the folder which created suddenly after updating ?
