Entering City Upskirts or Pony Horse Ranch from the overworld gives me a crash (Windows).
In js/plugins.js, "Dim Color 2" property of "Olivia_MapDisplayNameCore" is set to "rgba(255, 46, 95)", which is missing an alpha value. Adding any float value there fixes the crash. (This is an auto-generated file, so I assume the true fix is in changing some in-editor setting.)
