Thanks for confirming.
Ok, so I also used the commit immediately before the "[Satconfig] setup tuners FBCLink remove all 1.2 diseqc mode (#2857)" commit and so far okay.
For anyone wanting the commit immediately before this one then back-up existing files by renaming to something like .old instead of .pyo and extract files in attached rar to where these two files go...
/usr/lib/enigma2/python/Components/NimManager.py
/usr/lib/enigma2/python/Screens/Satconfig.py
