On fresh install after configuring AML to support Duplicate Mod Ids and then setting LWOTC Experimental (1.2) and Highlander Beta as the "preferred duplicate", the remaining missing dependencies show up. I crossed out the ones you mentioned in your instructions to leave ignored in case its useful to someone else in the future who might come here not being super familiar with modding xcom 2 like myself.. but some missing dependencies remain unmentioned so I was hoping you could clear those up before I start a new campaign and have to deal with any mid game mod issues?
