The DynEMC system looks like it dosent recalculate vanilla crafted items when an item is changed from its default value. (Ex. redstone changed to 5 but piston EMC value not adjusted to match, or any vanilla crafting recipe using redstone).

From what i understood, it calculated crafted items from their base items used to craft. Any mod-added items that used redstone in their crafting recipe got calculated properly however. If these values are actually supposed to be static, that would be great to know.

All of the static values are in this class.
