Ok,
I tried loading set s_language en from the console, and that didn't change anything.
Of note, I did some looking around, and in the config.cfg (attached- don't think there's anything personal in there besides my name) is a line reading 'set s_language "en" a'.
Attached is the console log from after I manually tried the set s_language en from console.
Of note, there are a lot of "no translation for xxxx.txt" at the end of the log - don't know if that's significant or not...
Thank you for taking the time to look into this. I had somewhat given up, which resulted in my delayed response. Now I know you're working on it, I'll be paying much more attention.
I have the same problem
