Help Collision marked as Trigger not collides

[mmortall]

Obi Plugin v.3.5, Unity 2017.4.5f1 LTS
Collision marked as Trigger does not collide with cloth during simulation.
I've added a temporal fix in Oci.cs in two Set functions, see coding example below.

Is there a reason for it and can I turned simulation on also for trigger objects? Thanks.

ps. Also turning on/off isTrugger not makes collider dirty for Obi, so you need to disable and re-enable it for making them counted by Solver. 

Code:

        public void Set(UnityEngine.Collider source, int phase, float thickness){
            boundsMin = source.bounds.min - Vector3.one*(thickness + source.contactOffset);
            boundsMax = source.bounds.max + Vector3.one*(thickness + source.contactOffset);
            translation = source.transform.position;
            rotation = source.transform.rotation;
            scale = source.transform.lossyScale;
            contactOffset = thickness;
            this.collisionGroup = phase;

           //for some reason trigger colliders are not taking part in the simulation
           this.trigger = false;// source.isTrigger;
            this.id = source.GetInstanceID();
        }
