WARNING:General:Failed to set non-zero loop type for animated single on load

Think this relates to a badly-set value in an ALE file. It's not a problem per se, but should be resolve at some point.

Start by reproducing the warning for an animated single and inspect the ALE value suspected in the report. No file, test, or entry point is named, so locate the code that loads ALE data and emits this warning. Done means the invalid or missing loop type is handled and the warning no longer occurs for valid animated-single data.
