So, I built the occulus, the inscription table and the craftign altar and now, every time I so much as look at their direction, the game starts to slow down a lot... If I move further away from my base, the lag stops. I tried removing everything except the crafting altar (too lazy :p ) and still nothing.
On another note, for some reason, after breaking and placing the occulus back, I could not open it, a strange message popped up (mysterious powers yadda yadda ) and my mana bar + burnout bar were gone.
What should I do?
I have windows 10 64 bit and I have curse allocate 10 gb for minecraft. All this happened in singleplayer.
EDIT: Fixed. Just remove all the AM2 blocks and put some other block in their place, which you will then remove and voila, problem solved.
Had the exact same issue. Been checking each time there's an update to see whether its gone away but I've taken to generating my world without Ars Magica 2 now, rather than deal with resources for a mod that slows my game down.
