in the Build menu are
1. 3x Coal Oil Synth... (1x Early ...)
- the 3. should be named "Coal Oil Synth (early)" ... that you have all 3 together
- 2 of them should have a tag like "obsolete"
2. "Military Fortress" should just be Fortress ... then its grouped after "Fortification"
3. under "Build Transport" is an Emplacement ... for what is it? ... what will it transport? ... is it the same as the Gun-Emplacement without a Gun?
... this brings us to point
4. some (more and sometimes useful) description to the buildings or an ingame wiki/pedia (like Civilisation) would be helpful
thanks
