thank you so much! You are absolutely right.
Unfortunately, i found out my problems got very very deep.
This “av_n” chrashed my game at 11% on loading screen. After reinstalling it, i got another crash at 12%, and at 16%,17%…. so on. I gave up.
It started by me trying to be a smartass, editing a few train-model files, because i wanted english description, not german.
When i finished, i started the game and got that cascade of errors.
Silly me I only made a back-up of the files i edited. I should’ve made a backup of the whole game! Anyways, now the old savegames don’t work and i’ll just get used to this and remember, never to edit vehicles ever again. At least not without full backup 🙂
Thanks anyways and happy holidays 🙂
