Minecart mania has the ability to limit how many saplings the minecart carries, so the need to incinerate them is rather pointless. Also, needs to be bigger. But very interesting set up for the trees.
minecart mania oesnt limit them to my knowledge as i need to remove saplings from my survival farm so the cart contunie to cut down trees, the same thing happens with micko888's farm
so unless you need to add a command to the sign or oli turned it off then it doesnt limit the amount of saplings it picks up
also if you think we could change it lmk!
the only thing i was thinking of changeing was making the platorms 1x1 with the saplings on top and the space between each tree being 1 block, when i get home ill make a quick one on single player to show you what i mean
