Hi Indzasa, thanks for the feedback!
I already have enough releasing in this next batch so I won't address Mini Trains but that's a good idea, I'll jot it down! The automation science pack costing wooden belts was intentional. But after thinking about it, I think I'll undo that change by default, since that's a 50% reduction in early-game wood demand, and is entirely negligible late-game.
I'll be releasing a set of updates soon addressing the Fulgora softlock, this feedback, and some other additions too for Cerys compatibility.
