9665	Not displaying conflict	naoliv	team	"Something is very wrong with JOSM.
I have download an area and removed a wrong way (154209524) from this data. Then trying to upload the data JOSM says:

{{{
Failed to delete node 1667801158. It is still referred to by way 154209524.
Please load the way, remove the reference to the node, and upload again.

Click Preparar a resolução de conflitos to load them now.
If necessary JOSM will create conflicts which you can resolve in the Conflict Resolution Dialog.
}}}

But there is nothing at the conflicts dialog! It's empty.

In console I can see:

{{{

}}}

The problem is that indeed I have removed the way but there is no conflict. Nobody changed this data and I have download the full area. It's a normal deletion, without nothing different.
The problematic OSM file is attached (there are 98 objects that I can't upload due to this problem)
