I see a line saying "Playername killed Playername using a ."
What is that?
Why is there no death message?

post your config

I got rid of most of my message problems by downloading the prefabs indicated on docs  page.

please manually download them from the following sites and store them in /data/DeathNotes/ with these names

• WeaponPrefabs.json
• EnemyPrefabs.json
• CombatEntityTypes.json
• DefaultMessages.json

Will have a look into that. Thank you.

Could also have been with a modular vehicle, I don't think that shows up with those configs

Could also have been with a modular vehicle, I don't think that shows up with those configs 

{
"KillerType": "Car",
"VictimType": "Player",
"DamageType": "*",
"Messages": [
"{victim} was flattened by {killer}."
]

},
"Modularcar": "Car",

Seems the message appears when someone falls.
Which is weird cause there is a category for Fall.
The only category that can be responsible for a message like "Playername killed Playername using a ."
is this one I guess:
{
"KillerType": "Player",
"VictimType": "Player",
"DamageType": "*",
"Messages": [
"{killer} killed {victim} using a {weapon}."
]
},

Now I know what it is.
The snowball gun! :D
Players use to shoot on the ground and hit themselves til they die.
So, how can I add the snowball gun to be named in Death Notes?

Ok. Deleting that message above completely did it.
