Yes the strings are not translated in polish, yet and the following strings must be added in Polish in
ub\tra\polish\ubdialog.tra
@345 = ~I need you to get it, and bring it here. I will dispose of it, and restore the balance beneath the city. If there are too few spiders then the vermin will rise up. The exterminators do not think of this.~
@346 = ~I have no master, and the one I owe does not know of my plan. No, this will not benefit him in the least.~
ub\tra\polish\ubsetup.tra
@1000 = ~Sarevok's Remorse~
1000 is only the beginning of much new added text.
If you have time, it would be nice if you can translate all the rest of the ubsetup.tra and the two strings of the ubdialog.tra in Polish.
