Q Light Controller+

for several reasons it happens frequently that I need to adjust the patch during the setup/rehearsals and since few months I've this annoying inconvenient:
if I change a dimmer number - e.g. from 5 to 15 - and then I try to patch another dimmer to the same old number - e.g. 5 - I get a message that the address is used and every time I need to reload the show.
Is there any reason for this behavior?
qlcplus 4.10.2/4.10.2b qt5 (probably other versions too) linux 64

confirmed.

steps to reproduce:
- add dimmer @ address 1, 1 channel
- change address to 2
- try to add dimmer @ address 1 -- error

Fixed in git. In the meantime, reloading is the easiest fix.
