Any way to modify the damage/radius of Rockets?

Some patches ago I was able to modify Rocket's damage and radius this way:

Code:

void OnRocketLaunched(BasePlayer player, BaseEntity entity) {
            var expl = entity as TimedExplosive;
            if (!expl) return;            //Modify radius
            expl.explosionRadius *= X;
           
            //Modify damage
            foreach (var damage in expl.damageTypes)
                damage.amount *= X    
}

Unfortunatly this no longers works because my variable expl is now NULL. Guess something in the game's code changed. Also couldn't find anything else that lets me modify the damage/radius in that hook.

Does anyone know a workaround for that? I want to modify especially Rocket damage, not explosive damage overall (c4 etc).

 

Oh well, thought I couldn't expect a fix for that according to the Github issue I made.
Thanks a lot
