You definitely have problems with your interjections interfering with those of other mods that were installed prior to your mod. On my first runthrough, I had installed Sirene last, and the initial contact with Demogorgon was screwed up. On my second runthrough, I installed Sirene first, and there was no problem with Demogorgon. I have my suspicions about other areas of interjection intersection with other NPC mods, but have not taken the time to make a thorough investigation of it.
May I bring to your attention INTERJECT_COPY_TRANS4 which incorporates the protections of both ICT2 and ICT3.
I like your mod very much. I hope you will accept these comments as an attempt to help you make it even better.
