More specifically, the barterbuy and bartersell dialog topics have some response lines that exist in the SI version of Oblivion.esm, but not in the non-SI version. If I modify the result script, or the conditions for one of those and load the plugin with the non-SI Oblivion.esm, what will happen? Those response lines all have conditions on the form "GetIsID SomeSIref == 1", which can never be true without SI, so the condition can never be met.
As long as the only thing that happens is that the response lines are ignored because their conditions cannot be me, then I'm perfectly happy, but I'm afraid this will cause the game to crash, or create havoc with the non-SI responses too.
Do anyone know, or do I have to somewhat make a non-SI install to test?
