Yes, BetterLogistics is technically identical with Workshop mods, so they don't work together (and there would probably be some issues if it was possible to activate both). Same problem for Sniper's 'Four Character Creation' (both on Nexus and Steam).
I wish there was a patch one day that allows multiple (editor created) mod activation. From what we know (I've never tried but others told that) it isn't possible at the moment. So you'll have to make decisions here (6 players, 4 character creation, XC_Bags, BetterLogistics etc.). Maybe there'll be combined versions of some mods in the future, but that's often nasty work for the creators.
