That happened to me, too, and if the issue was the same for you I have a fix. The thing is that earlier, the URL would start with "herofactory.lego.com" and that was recently changed to "lego.com/herofactory". Thus the web player wouldn't find the correct save file on your computer as it is saved locally. You need to go to this folder on your computer:
%%APPDATA&&\Unity\WebPlayerPrefs\cache_2elego_2ecomOn Windows, just paste it in the Explorer address bar
/Users/[YOUR USERNAME]/Library/Application Support/Unity/WebPlayerPrefs/cache_2elego_2ecomOn Mac, should be like that or similar but I can't verify
Then you need to rename this file:
prefr-herofactory-_2d-media-franchises-hero factory 2014-games-invasion from below-webplayer_5f20131223_2eunity3d.uppinto this:
prefr-www-r-herofactory-_2d-media-franchises-hero factory 2014-games-invasion from below-webplayer_5f20131223_2eunity3d.uppThere should be a new file with the latter file, that one has stored your new progress. If you want your old progress back, replace it by renaming the old file.
