I was wondering if something more is changed how maintance currently works, because the production of MSP is slow right now or difficult to increase quickly.
Yeah, that's my experience well, but I haven't found it to be problematic yet, as I have so far been able to keep up with fleet maintenance.
Previously it was possible to produce a lot rather quickly with industry, but I think it might be helpful to consider MSP a resource of a similar kind as fuel. You can't produce a lot of fuel very quickly. You can build lots of fuel refineries, if you are low, but you learn very quickly (once you have your first fuel crisis) that it is essential to think ahead and
plan your production. A slow and steady production.
