Nihil not working wiith Weapons on SkillSystems?

I was trying some stuff in Febuilder, when something odd happened. Apparently, if I use a weapon with Nihil assigned, the effects of trigger skills like Pavise or Aegis activate anyways. I don’t know why this happened, but I suppose it has something to do with Pavise nullifying everything about the weapon?
Notes:

  • Nihil as a regular skill on a unit works just fine and stops Pavise and Aegis.
  • The weapon activates other skills like Fury or Rallies like normal, the problem seems to be with just that combination of weapon nihil + enemy pavise.
