Thanks for the feedback, I haven't given up not at all! Just testing as I go :). my new biochambers mod tweak is keeping me occupied, but I will definetly revisit the destroyers mod and see what I can do make it work :)
See i hear what you're saying but that 'difficulty' just kind of dissappears in 2 seconds because steel will become pretty easy to mass produce in the late game. The reason i made this small tweak was because the steel furnace was an 'end item' that had no purpose. Unlike the stone furnace which is used in other recipes. Hope this makes sense :)
