(PLEASE HELP!) Changing collision rules within a callback is likely to cause crashes!

[[XGN] XLency]

I run a Star Wars Roleplay server on the new update, and whenever I try and use a Star Wars Air Vehicle it spams this in my console! : Changing collision rules within a callback is likely to cause crashes!
PLEASE TELL ME HOW TO FIX THIS!!!
P.S. Server is 75.82.231.13:27015 if you want to come to me in person.

Don't escalate.
That message says nothing.

It also lags my server a LOT. I wish there was a fix. It gets annoying when it spams my console.

The message was introduced to let addon developers know they are doing something wrong.

So you have 3 options:
1. Fix it yourself by rewriting the code
2. Get the addon developer to rewrite the code
3. Ditch the addon.

I had contacted the addon publisher, but so far no response.

What is wrong with changing the collision group on PhysicsCollide function of an entity, resulting in removing the PhysicsCollide function?

For some reason even this causes console to print Changing collision rules within a callback is likely to cause crashes! but I'm not changing collision rules with SetCollisionGroup.

function ENT:PhysicsCollide(data, phys)
    self:Remove();
end;

Setting pos or removing entity with PhysicsCollide causes console to print this error, am I doing something wrong?
