Is there a way to reset instances of Launaris Temple level 3?

So a bug appeard, we have done all of the mentioned steps bu still, it didn't work.

Tell us the steps you used to reset the instance. I think you must be doing something wrong.

i have troubles with the reset of chamber of sins 3 ...

even after i went to sleep it's still not reset.
i went to other areas waiting for the reset but still doesn't ...
i tried the right-click on the waypoint on chamber of sins 2 and waypoint of Crossroads didn't work either ...

what do i do now???

It sounds like you are confused about zones and instances. Crossroads is a zone by itself. Chamber of Sins is a separate zone from The Crossroads. Chamber of Sins has 3 levels. Each level is it's own zone and can be reset individually. It does NOT have a separate boss room like the Warden.

To reset a zone you Control click the entrance. You can CRTL click the entrance when entering from another zone, or CTRL click on the world map when you use a Waypoint. When using a waypoint, you CTRL click on the map itself, not the waypoint.

If done right, you should get a screen that gives you a choice of selecting a new instance, or entering an existing instance. Click the choice that says "New". If there is only one choice it means the zone has timed out and reset on it's own. This also works when entering town, which also have instances to keep them from getting too crowded.

Here is a flow chart for Act 2. Each rectangle is a zone that can be reset. Blue dots represent zones with waypoints.

And here's Act 1. Notice that there is no rectangle for the Warden or Merveil. That's because they are not zones. They are part of Upper Prison and Cavern of Anger.
