i also agree that EE can be overpowerd however some items from this mod are very usefull like the Alchemy Bag , Alchemical Chests and Transmutation Tablet but thats about it
somtimes with the signal blocks... if a signal block was selected to pair then you delete it it stays waiting for a second signal block to be paired but it cant because it is not there anymore... removing the survayor from your inventory and crafting a new one should resolve it. i have had this problem many times
