NullReferenceException at AllowDamageError

I see an exception in the server console when a destructible roadsign is it with a vehicule. I already added a new rule that anyone can destroy roadsign

"anything can hurt roadsign",...

{
"name": "roadsign",
"members": "roadsign1, roadsign2, roadsign3, roadsign4, roadsign5, roadsign6, roadsign7, roadsign8, roadsign9",
"exclusions": ""
}

post the exception

After the latest server update and oxide v2.0.4830, I cannot reporoduce the issue anymore.

FYI, this is the message before the server+oxide update
