Hi, hope you don't mind me posting here as I don't have permission to use the bugs forum.
I have had several problems since I started playing a couple of days ago on a single player survival world (3.1.2). Firstly, NEI stopped working. Secondly, after I built a solar array I realised that the IC2 wrench would not change the position of the output. Finally, thinking that if I switched back to an earlier version I might be-able to fix these problems, I did so; this resulted in half of my house disappearing along with most of my items :S.
Does anybody have any suggestions? Has Tekkit always been this buggy or is it just the new version?
