Hi guys,
Look this, I made exactly same Inline 4 Engine insane Military Gent Set in sandbox but some data not confer
That might have to do with Tech Pool.
Edit: I was completely wrong.
Sandbox is using different calculations than the scenarios. The scenarios have to use the version of the calculations that the specific scenario was balanced for, so there will be deviations.
Well, the fuel economy was buffed a bit after this scenario got balanced, I guess, and also, scenarios give the total costs (including labor costs), while sandbox gives the material costs only.
Ok, I was thinking have found some bug, just trying help, thanks
