Passive skills ignoring required tech?

[Sgt. Johnson]

Noticed while testing an event in my map that some of the creeps that I had given a passive skill to were gaining the effects of it when they would only be given it if the players were playing on a higher difficulty (ex. Zombies having a reincarnation ability) is this a known issue or just some weird random bug.

I've got this issue also. It also seems to happen on abilities such as Black Arrow.

1. is this creep owned by Neutral Hostile or Passive?
because I don't think that the Neutral consider required tech...

2. are you sure that you have make it require a tech?
I mean try add the passive abil to your own unit and see if it has required tech or not...
