I have no clue what's going wrong here, I tried to fix it myself but I am litteraly green at modding. Secondly I use the GoG version so I can't post in comments sadly enough

It's regarding 2 patches that add the bookshelf and the recipes from Human Resources to the thinkingspot, if this doesn't happen you can't advance in tech due to lack of the tech 'methodical research'

I worked around it by giving that knowledge to my starters, but I don't know how to fix the patch itself.

- Study Desk doesn't contain proper recipes
- Thinking Spot doesn't
- Can't advance in tech at all this way, I guess it's a simple xml fix?
