This is a Rimworld mod made for the Progression modpack by Ferny. (https://steamcommunity.com/workshop/filedetails/?id=3521297585)
If you are not using the full pack I am currently unable to offer support.
This is not compatible with GonDragon's Tech Tree https://steamcommunity.com/sharedfiles/filedetails/?id=3328259983 that is in the pack, you must remove that before using my mod.
For a little more flair I suggest you use Research Tab Colors https://steamcommunity.com/sharedfiles/filedetails/?id=3108740804
