I hope this goes here. I am using the Direwolf20 1.6.4 mod pack newest version .20. Whenever I switch ages with mystcraft my AE system is powered off when I return to the overworld. I have tried to break blocks and replace them nothing works. Yes I have power. I was just wondering if anyone has run into this problem before? I tried to recreate it in a test world and it worked fine. If my game is corrupted is there a way to fix it? Just curious it is annoying would prefer not to start all over again. Thanks in advance.
