Mining Stone
I dont know if other people have experiences this within the modpack, but im having an odd issue with trying to mine vanilla stones. Things such as stone, granite, andesite, and diorite all take a longer amount of time to mine than everything else in the game that requires a pickaxe. As in, using an iron pickaxe takes 5 seconds, while trying to mine iron with that same pickaxe only takes 2.5 seconds.
