When I power off my S4 LED fixtures, they have lost their settings when they power back up.
Description/Explanation of Issue
This issue affects both Series 1 and Series 2 fixtures that are being run in Studio mode, and will only occur when the source of data feeding the fixture and the fixture itself are powered off at the same time. So, for example, this could occur if you have a run of DMX going directly from your console to your fixtures, and you power both the fixtures and the console off at the same time.
This issue does not appear when either the fixtures or the source of data are powered off separately, and does not affect any fixture modes other than Studio.
The issue was resolved in firmware v1.8.1, affected users should upgrade using UpdaterAtor
