CMS Made Simple Forums

I am using FEU module on a Polish website. Currently fine-tuning the templates and testing them. I noticed that Forgot Password form uses info from pl_PL.php to display the form as it is supposed to, but after submitting the form everything (title, message, error message, labels, etc.) are in English.

Anyone knows how to fix that? Should I put any hidden input to parse the alternative lang setting?

This seems to be a bug. The "lang" parameter doesn't make it past first display of the forgotpw form. Tried to research where it gets MIA, but couldn't find after a few hours of sifting through the code. Will report a bug in the module. However, at a very least I found a workaround: I placed

<input type="hidden" name="cntnt01lang" value="pl_PL" />

right before {$endform} in the Forgot Password Template. Works for me.
