Cloaking and nebulae

[Q]

The description of the cloaking devices is not correct:
With level IV sensors you will see ships with level IV cloaking or in a nebulae with level IV obscuration. Otherwise you would have cloaking that can't be beaten, which is not the case. However the natural occuring nebulae with level V obscuration and the mines with level V cloaking can't be seen with any sensors.
