Bug: Hog4 behaves strange after Fixture Editing

I observed the following on the ROadHOG and on Hog4PC:

If you use your own fixture in some cues and you edit it, for example you change the meaning of a DMX channel from Intensity to DimmerControl because you have made a mistake during the creation of the fixture, the HOG4 does not control this fixture in some channels anymore. You cannot change some values with the encoders for example.

You have to reboot the software or the Hog4PC. After that the fixture is usable again as usual.
