So, considering long war of the chosen mod is now a thing, I've attempted to run it with this mod, considering that it also has unequipping. I haven't seen any effect from it. No conflict messages, no buttons from this mod popping up. Maybe it's cause LW2 is not enabled? I tried to set it to ignore that (in the xcom 2 alt mod launcher) , but i have no idea if that worked.

The only mods I use that should change squad select is robojumper's thing (as it's required), and LWotC.

Edit: I've found a mod that works (as far as i can tell): Remove Weapon Upgrades. It adds a button for removing upgrades in the squad manager (and some other stuff, but that was what I was here for). Freaks out a little for half a second whenever you go into squad view, probably becuase robojump's squad select, but it works.
