I ran into a problem with the shields where they suddenly started eating away at their durability. With Spartan Weaponry, there will be weapons that give mining fatigue to lower attack speed depending on how big the weapon is. So if I switch to any of these weapons, the unenchanted shield goes crazy by infinitely trying to remove the effect. But it is not necessarily an issue with Spartan Weaponry but that the vanilla and spartan shields are acting this way without the enchantment. Looking at the crash log it seems the real problem has to do with both this mod and Apostheosis. Which is strange given there wasn't anything related to shields described in the Apostheosis' page and this problem was not present for a long time.

My bad, already fixed. Always check the changelog of the recent versions.
