Hmmm, it's working now - ModuleX= was being reordered in the project file and the .meta order was always straight 1,2,3,etc. For some reason it wasn't changing... I was reordering tabs to check for changes then removed an image file to tidy up in the process and after that, and re-adding and removing the meta from source control, the meta file is changing. This was a project started in a version previous to 1.8, used in 1.8B and now in the 1.8 release version so it might be a hiccup due to that.
