Andy:

Mine does not work properly either. The cargo load works but the fuel load does not. This problem is actually mentioned by one of the reviewers (on AVSIM I think) as not working properly. I assume they are working on a fix ??? But I don't know.

Oh, and the cargo load depictions in the ACE are just that (I think) as I do not see any actually containers in the hold. But as I said, the proper "weights" show up in FS.
