Nope, giants team is lazy, many more than players/modders. Just watch the ricebags recipe. 100 rice = 45 bags by cycle. rice liter = 1.1 and ricebags = 1.47. 100*1.1=110 and 45*1.47=66 so we need a factory to transform 110€ of rice in 66€ of ricebags..... And never fixed that sh... since the release !
Luckyly, your map will have a true factory where to produce profitable ricebags (but without cartonroll ) :D
