When I change a vue template in vue2 dev environment I get "Error: Multiple conflicting contents for sourcemap source" — according to this link I added needMap: false, to the vue rollup plugin, so I get the error but the page reloads now and it breaks sourcemaps for SFCs. vuejs/rollup-plugin-vue#238. Might be able to do better than this? Not sure.
