[2020] skills automatically at level 7

You are using outdated configs, make sure Difficulty.eco looks like this:
{
"CollaborationPreset": "MediumCollaboration",
"DifficultyModifiers": {
"SpecialtyCostMultiplier": 1.0,
"SkillGainMultiplier": 1.0,
"SpecialtyExperiencePerLevel": 25.0,
"CraftResourceModifier": 1.0,
"CraftTimeModifier": 1.0,
"PlayerExperiencePerSpecialtyExperience": 0.0
},
"EndgameCraftCost": "Normal"
}

Update 9.1.2 fixed this, so you do no longer need to edit your configs.
