Thanks for your fast reply.
This is an issue and has been for months now. I ran into all those other issues you describe for myself.
Using regular mouse in 2D, selecting models, I have never seen it happen with an entity, just uploaded models.
This is a constant issue, lots of people have seen it, and its pretty regular.
It happens every day several times a day in any and all situations.
@Richardus.Raymaker describes it exactly.
When an object loses its identity or whatever happens, its gone for all click intents and purposes, I cant click it from any angle no matter how I hold my mouse, it is invisible to the click. There seems to be a problem with the servers association with the object, I move close and further away no click, I change my angle no click, I even relog still no click, the only thing that reliably brings the click back is to restart the server.
I can however always select it from the Entity list, and in some cases this selecting from the list restores the clickability, but not always.
As Richardus describes, your click lands on the object BEHIND the subject so this rules out me being inside an entity, and rules out something in front of the entity, and rules out a bad click. There is a click but it misses the target and hits whatever object is directly behind it, once it happens to an object it will do this reliably until I reboot the server.
Generally it happens when I first import an object, about 5% of the time, when I click off the imported object to another object, I cannot click the first object back again, I have replicated this on an empty field with just one entity.
But it cannot be reliably replicated, I can work for 3 hours and not see the issue. then it might happen for 3 objects on the scene within minutes.
Thanks for looking into this.
