This isn’t exactly a bug, but it’s still an issue.
I have this set up. Oil well goes by truck to train station(4 opel bliz, 60s interval). Train station goes a looong way (1 RE 2/2, 10 mins interval) to refinery and comes back with goods.
However, the refinery also has another oil well nearby that supplies it with 25 oil without asistance from me. That oil field doesn’t grow past 25 production.
The problem is that the oil refinery caps at around 33 production, and the oil well I’m servicing stays at 5 production, even though there is demand for the refinery to go to 100 or more. This is the second game I’ve noticed that supplying an industry fron 2 different sources causes the industry not to grow, so I thought I’d report it.
Happy hunting !
