Does anyone have any issues using QGIS (current version 2.12.1 on mac) with the British National Grid CRS (EPSG 27700)?
All of my data is held in BNG and my workspaces are set up to default to BNG when I create new datasets. However, almost every time I create a new dataset (raster or vector) QGIS defaults to creating a user generated CRS; an example in the image below. These are always slightly out of sync with the 27700 data but shift back if you change the CRS to 27700. Sometimes I'll finish working with 10 different user CRSs.
Is this something that I'm doing or is this a bug? I can't remember whether this has ever happened on previous versions of QGIS.
