I have been using the convex hull tool to create MCPs for various layers (containing location points). For some reason, this layer is not looking like the others and I can't figure out why. It's as if it isn't including all the features and is thus producing a shape not at all representative of the actual spread of points. I have checked the features and found no noticeable errors and I have even tried manually selecting all the features and using the "use selected features only" option when running the convex hull - this hasn't worked.
Am I missing something super basic that is messing up my MCP? I'm using QGIS version 3.1.
