13.0.20 has a bug that causes pt-BR translations to appear... I don't know how to express it exactly... hmm... one position before where they should appear?
For example, the "About PowerArchiver" menu entry (in tabbed mode, I don't know about classic) is the last one in the "?" button on the top-right. But, there, the translated text says (roughly) "PowerArchiver Auto-Backup Script". Clicking it brings up the about window, as expected from the last item in the "?" menu, so the functionality is as it should, it's the translation that's wrong. Now, the item right before the about item, the one that goes to the skins download page? It is the one that's saying "About PowerArchiver". Clicking on it goes to the skin page in the site, as is its functionality, but the text is wrong. And so on and so forth: every single string in the whole program is displaying not the translation for its actual text, but the translation for the text that follows it in the translation file.
The funny thing is that, due to this, I cannot find in the options screen where to change the language. Everything says something that is actually done somewhere else, and nothing does what it says. It's so crazy it's even fun.
