When an AI gets radded, it becomes invincible for ~4 seconds.
This is normal.

However, with the base radiation weapon, the Curie or whatever from Vervaardiger Processing, after irradiating an enemy it will hit it again with the rad weapon to make it invincible again, basically firing at it forever which a base tends to do to radded AI, but in this case every time it hits the AI again with the radiation weapon, it causes the invincibility to trigger again, making it invincible for ~4 more seconds, at which time it will not fire since it will do 0 damage, until it wears off and goes invincible again and infinitely repeat.



I'm not sure if radding them again, that it's intended they become invincible for a few more seconds, I assume this is a bug and they should only be invincible after being irradiated for the first time.

The screenshots are taken in Xu, if you want to see the behaviour in-game. The bigger greens will be there for a while I expect.
