Hi Martin eaec752 looks like it should provide clarity. I would like to be able to compile a dataset that activates this code (for curiosity and maybe user testing), but it seems now that 'my therion' has downloaded the transformation grid once, it resides somewhere on my machine (I cannot manually find it though). It seems like it has downloaded the entire NZTM grid (as the documentation says it would) and so any locally compiled cave dataset no longer needs to download the grid (which in the normal course of events is good). I have compiled therion datasets for caves in other parts of the world, but none have triggered this code. I presume the grids they use are already built-in by default.
So for the sake of curiosity, is it possible to get Therion to delete an existing (previously downloaded) grid and so subsequently trigger the need to download it and test the eaec752 change? Will using cs-def to set a null string for NZTM force it to be downloaded again? Or will it cause proj-missing-grid to behave as though it is set to ignore (even if download is specified)? Asking before trying it in case I end up breaking something that is hard to fix!

The latest commit provides additional information about downloads now. Caching is more tricky: we just enable it and Proj then downloads just small parts of grids relevant to your area and stores them in its database without letting you know what exactly got downloaded.
