Observed behaviour:
* Get a lathe in range of an emitter and an enemy energy mine
* There is NO setting that will make it fire at the emitter if the mine is alive (even "emitter" won't work)
* Omnis suffer the same issue
What I expected:
* That the "emitter" setting would attack emitters first
Why this is a problem:
* What should be a 30 secs attack on an emitter becomes a gruelling 5 minutes battle as the emitter lathe rebuilds the energy mine again and again.
To add to this, I find that excessive particles will rebuild a mine even if a lathe should deny it all together due to how little health mines have.
I also found out that changing the setting to structures does not make the lathe stop firing upon an emitter even if a spawner is in range too.
