Any way to protect Horses from the Attack Heli?

I know TruePVE is not meant to control damage to animals, but it works when players are involved. No matter what I do I can't get any rules to be assesed when its Attack Heli/Bradley vs horses that are not being ridden at the time.

I haven't posted the config to pastebin as its not even getting to the stage of considering rules as it sees the target as a non-player.

From: TimedExplosive, rocket_heli
To: RidableHorse, testridablehorse
Checking exclusions between [empty] and [empty]
Shared locations: none
No shared locations, or no matching exclusion mapping - no exclusions
No exclusion found - looking up RuleSet...
Using RuleSet "default"
Initiator is heli, target is non-player; results: allow and return

Hi, rules do not apply to helicopters. It uses flags only. I can add a flag for horses !:p

Awesome, thank you.
