It's come to our attention that there are some issues with the Polish translation that went live last week, including some missed translations and some font-sizing issues at certain resolutions. We'll be working with Cenega and QLOC to rectify these issues as soon as possible, and are hoping to issue a patch to solve as many of these issues as possible, tentatively next week. Thanks for your patience!
Edit: These issues have been resolved in the latest patch (1.19.x.7). To get the update, simply launch Torchlight II.
