I've been playing Tekkit for a week or so and yesterday I experienced a sort of "déjà vu", as in a made a single chest to a double chest, put more ore in there, went mining, came back and it was a single chest again and I think I lost the ore.
I also think that my over-clocker disappeared from my extractor also.
Don't know if I'm going crazy or if this actually happens :S
Thanks for any enlightenment
