Hi. I am a Korean developer. I find one error and report it. The link below is missing an image. https://docs.unity3d.com/kr/2019.1/Manual/nav-NavigationSystem.html If you change the language in the upper right corner to English, the English version of the document will be loaded. There is no missing image. In the html source, the Korean document had an extension of svg, not png. I'd like you to fix this problem. Thank you.
