So I came back from lunch, and resumed chicken egg crafting. Ordinary day, right? Nope.
Lo and behold,
You made Chicken Egg (x40) -600 energy, +720 iMG.
While previously, I encountered the bane of any level 60's existence:
You made Chicken Egg (x40) -600 energy. You'll receive no more iMG from making these today. The creation process has ceased to stimulate your frontal cortex.
Thanks TS for letting us level 60's get iMG from crafting once more!
