Maybe moving thinks around caused the seal to start leaking. This is why its best to replace as many seals as possible when doing a transmission service.
Thanks, I'll take a look at them tomorrow morning. I have noticed that the electrical connector is usually covered in fluid so it's likely that it is in fact leaking from there as well. I think I may be redoing the job and replacing all the seals to be safe.

I did follow the torque order, however I didn't have a torque wrench at the time. Is it possible to cause damage to the gasket by over torqueing the bolts?

Yes there is, especially if you're reusing the same bolts. BMW rule of thumb, ALWAYS use new bolts.
