When the warden falls and lands from the sky,it creates an explosion.Every explosion name and its tables from the game is located in explosions.xtbl from misc_tables.vpp_pc.Open up explosions.xtbl and search for :
<Explosion><Name>warden_arrive_land</Name>
Then edit the following tables from "warden_arrive_land" section to your liking:
<Damage_Max>[your desired value]</Damage_Max>
<Damage_Min>[your desired value]</Damage_Min>
Changing both values to zero didn't fix the problem, any other ideas?
Try changing the impulse to 0 as well.The impulse ragdolises the npcs and detaches the movers off the ground.
Unfortunately, that didn't work out - what about radius? Also, there is another entry titled warden_arrive_fall - might disabling that one help too?
