I've finally finished the update of the German translation. All tra files have been modified. The update is based on the files of the current v13_120121 beta release.
Most notably, all texts in sound_tmp.tra have been corrected to match the actual sounds. For GORIN14, I adjusted the line slightly and decided to go with "Hier entlang, werter Herr, hier rüber!".
ubvial.tra has also received a rather comprehensive update that delivers some great improvements in style and expression, and I believe those lines sound much better now.
To a lesser extent, I revised ubcre.tra, ubedie.tra and ubscar.tra. jastey, I hope you approve of the slight tweaks I made to your new lines as well.
The other tra files were updated incorporating mostly minor corrections and some mild adjustments of expressions. I went through all texts to look for remaining orthographic mistakes and corrected them. I also added and expanded a bunch of comments, especially in extra_tmp.tra, in an attempt to harmonize the texts with the predetermined BG1 strings, or explain deviations, respectively. Furthermore, I translated the English line @115 of setup.tra.
In terms of content changes, as promised, I adjusted the description of the Wyvern Head to specify a weight of 30.
I did a test install (BGT) using the updated translation and didn't encounter any problems.
The files I'm submitting should directly replace all existing tra files at bg1ub\tra\deutsch, no need to substitute the texts by hand. I've uploaded a rar package using my SHS account again. Please let me know in case this doesn't work.
