Hi
I tried downloading the latest version from this URL: https://www.babylonjs.com/versionBuilder/
After nothing happened when pressing "Generate", I checked the page source and found what I think is a syntax error. The download link (generateURL in index.js) does not end with a slash (/), so when generateUrl() adds a question mark (?), the link becomes invalid. Adding a slash seems to do the trick.
When downloading from what I think is the correct link (http://babyloncomponentselector.azurewebsites.net/api/buildbabylon/?stable=true&minified=false) the file is named "babylon.custom.js", when it would be nicer if it was named "babylon.2.5.max.js" or something - but maybe that was because I screwed up the download link by not adding any "&components" to the end?
