Discovered something not cool today. Playing Forever Stranded, finally at a point where I can think about setting up a fully automated resource system instead of my semi-auto system currently in place.
So, built a Igneous Extruder, was confused by it's recipe needing a Redstone Coil, plonked it down, and was horrified that it now needs RF to generate cobble. That I threw into a chest cursing the waste of resources I spent on it (given how annoying it is to get iron and redstone in this modpack, that was hurtful! My RF generation is also very pitiful again due to iron/redstone shortages)
So, switch to the tiny progressions cobble gen and then built a pulverizer to turn cobble to gravel, to then be shocked that this now makes sand. You need plain stone to make gravel! Don't know if this is a Thermal change or a modpack change, but again I sat there cursing this change. But, at least I can now abuse this to make sand using 1 pulv instead of 2 in earlier versions.
If these are CoFH changes, they are not very popular to me atm
