AFAICS, mods that add new enemies seem not to be compatible with Angel's Exploration's Gathering turrets, since they need to register an on_death event to each type of different enemy units (at least from what I can see on the scripts...) and without that event that triggers the gathering action the turrets are useless, sadly.

Would there be any chance of adding that compatibility to this mod? I've looked into doing it myself, with I know next to nothing about lua and the fact that this mods adds so many new enemy types complicates matters a lot :/

From what I could tell, Angel's mod exposes an API for other mods to register new enemies.
