Right. We have a fix for this one.
We are not able to reproduce it. Could you point us to a scene for which it happens, and which triggers are affected?
Do you mean that the trigger position is lost, like described here: Change trigger color/opacity needs always set new position V2.3.1 - #2 by wojtek ?
Do you mean it’s not possible to assign an Object type trigger to some surface with a texture?
This issue sounds like it’s related to a particular scene. Could you share the scene with us, and point us which surface it is?
