Hi, As GunChleoc: I just built and Launched the leper branch in Ubuntu 13.10 - A big thank you (Leper ...) for fixing this problem But as Lion.Kanzen (apparently), I have no other choice than "English (United States)" in "Tools and Options"> "Language" I tried several things (after looking in /home/loki/0ad/binaries/data/config), such as changing file /home/loki/0ad/binaries/data/mods/public/l10n/.tx/config file or /home/loki/0ad/binaries/data/l10n/.tx/config file to point to the French .po, replace the fr.po that I found by those transifex, but without success Without being oppressive, but being so close to a major advanced (in my opinion), how can we put the desired .po ? Edit : I had not read It is now possible to switch from a Latin language to another (even with space problem) ?
