download info says:
the github guide saysinstall via a mod manager and overwrite your current TTW install.
alsoIf you are updating from an old version of a mod, you should select Replace
so i chose "Replace", and it deleted ALL the files in the mods folder like WTF!!Install & activate it as you would any other mod in MO2 and allow it to overwrite Tale of Two Wastelands in the left pane
now i have to reinstall from scratch and convert all the files again...
