Here how I did test. There 2 custom vepa files here: data\vehicle\07_european_01\part\paint

01.vepa  -  trigger pckd error
04.vepa  -  does not trigger error

Enable this mod, exit WF, will trigger a Cannot Free Slot **** /07_european_01/settings.pckd error.

Now remove the "bad" 01.vepa file from \paint folder, so just the 04.vepa file is there. Now start WF again, then exit WF, will trigger a new Slot **** /18_american_01/settings.pckd error. Game move on to the next vepa file that is "bad" in another car folder: \data\vehicle\18_american\part\paint


This what I found out today trying firure out what was causing my Fig8 track mod to throw off this pckd error.
