Biofuel depots started sending buses normally after that, even with the cursed bus station in the city, and everything is working as it should now! After playing around, what DID fix it - god knows why - was building a regular bus depot for the city even though it's not sending any buses, because all my bus lines are set to biofuel. But, changing the models manually didn't fix the problem for me. And yes, in fact, same thing happened to me: the models of the bus lines defaulted to regular bus after building a hub, hence the biofuel depots were not sending any buses. Tried it with the other transport hub that includes multiple bus lines, the metro-bus hub, and it triggered the bug as well.ĭidn't want to concede to not using transport hubs, so I googled the bug and came across this thread. Deleting a depot (so that a newer depot became the 'master depot') made it send few buses to my three oldest lines, but nowhere else? However, deleting the bus station fixed it and the depots started working normally again. Biofuel depots just refused to send buses to my 3 new lines, or any repaired ones to existing ones. What triggered this bug for me was building a bus station hub for my new airport. I had a 55,000+ city with already 10+ beautifully working bus lines. I had this bug as well - thought I'd add what helped me in case someone else also finds this thread when looking for a solution.
