This is my first time using BWS (and BWP), as all this years I've been unaware of its existence, so I'm probably making a stupid mistake.
BWS version is 20121202, the games are from GOG and the compilation being installed is "Tactic" BWP. I didn't remove or add any mods.

This compilation selects SoS, CtB and TDD. It also adds NeJ2 6.8. The problem is the installation stops because of this part in NeJ2's script:

ACTION_IF (FILE_EXISTS ~data/CTB-RULE.BIF~)
  OR (FILE_EXISTS ~data/SOS-RULE.BIF~)
  OR (FILE_EXISTS ~data/TDD-RULE.BIF~)
THEN BEGIN
  FAIL ~You may not install this mod with other big mods!~
END

So I'm not sure what to do. Should I just ignore it and continue? If they can't be installed together, why are they all in the tactic compilation?

Also, the mod "BGT NeJ2 Compatibility Modification" is selected. I think that according to the pdf, it's been marked obsolete because NEJ2 can handle the BGT compatibility by itself. It's not really being installed anyway, the log says "The condition to install the component at this point could not be matched.", but I wonder why this mod is selected.

Again, I'm probably missing something obvious, but I'm curious about the answers.
