Hi to all, gentlemen.

What can I say... I don't know what the problem is, nor can give you any clues. Localization of mod is ignored.

Everything is OK, or at least I cannot find anything wrong. References with due %, names are correct, xml syntax parsed ok, questguielement extratype called, localizationplugin, "english" subdirectory... everything as it should. Even localization files are named "ES2_Localization_" and whatever comes next, just in case that could be a problem.

Compared it to another example mods... followed all the steps. Nothing.

Game won't load localization files.

As a last resort, I put mod's localization files in base game dir... still invisible.

Here's some of one of the files:

<?xml version="1.0" encoding="utf-8"?>

    <!--THE TONKLIN HYPOTHESIS CHAPTER 1-->

    <LocalizationPair Name="%TonklinHypothesis01-Title">The Tonklin Hypothesis</LocalizationPair>

    <LocalizationPair Name="%TonklinHypothesis01-Description">The expedition has stumbled upon what it seems to be a cache of ancient knowledge. Written in an old Vilani dialect, the texts were sent to translation, and among other bits of info, a diary was rescued. It belonged to a figure of unknown racial background named Rehman Tonklin. He was, for what we have uncovered, one of the most prominent mathematicians of his time. The diary contained what in other side texts is named as the Tonklin Hypothesis, a math conjecture that has to do with an algorithm known as the Tonklin Zeta Function for complex numbers. The Function's analytical extension is related to the distribution of primes. Under the Hypothesis, all given values where the Function goes zero and the zero is nontrivial belong into a critical line of the real part of the number being 0.5, and it seems it never was proven or disproven.\nSolving this problem and making it a theorem can be a potentially groundbreaking advancement. The implications of discovering a closed formula for all those dodgy zeroes would open the gates for many other algorithms now in terra incognita. We can take the baton and continue where Tonklin and his followers left. Or perhaps the hypothesis was indeed proven true or false, and it is just we have't yet discovered where the solution lies buried?</LocalizationPair>

    <LocalizationPair Name="%TonklinHypothesis01-Title01">Test the Hypothesis</LocalizationPair>

    <LocalizationPair Name="%TonklinHypothesis01-Description01">Our mathematicians will for sure succeed where the ancients failed.</LocalizationPair>

    <LocalizationPair Name="%TonklinHypothesis01-Title02">Search for More Evidence</LocalizationPair>

    <LocalizationPair Name="%TonklinHypothesis01-Description02">More has to be discovered about the hypothesis and the solution, and the tool is archeology.</LocalizationPair>

As you may suppose, the quest which refers to this doesn't show up localized. Its gui element is:

Can't tell what the wreck is going on, gentlemen. Many thanks in advance.

Can you upload your plugin file?

Here it is.

By the way, I copypasted all localizationpairs on a vanilla loc file, and it messed all localization up, vanilla included. I'm currently checking the file again, but still can't find anything wrong. All <> and "" are there, and correctly put...

Hmm I'd need to investigate the entirety of your mod, would you be willing to zip it and upload it here? Or if not, dm me the zip?

Never mind, a night's sleep found the solution. I wondered if some <LocalizationPair> was not properly closed, and as there are tens of other </LocalizationPair>, the file would parse correcly.

That was the case.

Many thanks for the offer.
