Brand new QGIS user here. I'm on version 2.12.3 on a Win7 machine.
I've downloaded a vector layer as part of an assignment. After adding an OpenStreetMap base layer, the project placed my vector feature somewhere in Nigeria, when it's supposed to be in Navarro, the US.
What is likely to be the problem here? Both layers are on the WGS 84 / Pseudo Mercator (EPSG:3857), and I have OTF projections turned on.
