We have just reverted all Windows users to the old version of node-webkit (the underlying tech making the game run on PC). Sadly [url=https://steamcommunity.com/ogg/239820/announcements/detail/2901965686288048287]our latest upgrade[/url] to a newer version caused game hints and achievements to not load (nor save correctly). The good news is that hints and achievements previously gained should now load again so there should not be any data loss. Unfortunately a proper fix is anything but simple as the issue seems outside our control for now but we will investigate any possible fixes. Other than the fact that we are now again running on an older version and thus miss out on the nicer text rendering, there is no loss of features in this version on Windows. It still comes with all the new features like save-sharing. We have left the Mac version on the newer version as the old version has significant performance and display-compatibility issues. Hopefully we'll have another update to address this soon.
