Hi,
Found what I assume is a bug.
It appears that the OSC Query does not properly clear the previous fixture definition when changed.
For example, say I have a fixture named "100" that has 10 sliders defined. When I query MadMapper for fixture info such as
http://x.x.x.x:8010/fixtures/105/sliders
It returns the list of 10 sliders as it should.
If the DMX fixture is changed to a fixture definition that has four sliders, the query will return not only the four sliders but also the remaining six from the previous fixture.
After saving and reloading the project the data will be correct.
