Yeah when its uncommented it will spam the ghosting notification for blueprints over all blueprints. if you want it back on uncomment it? This is a fork after all not intended to be a full copy paste. I only forked this to make it work with 2.0 because Kitch was taking his sweet time updating his mod.
This mod was made as a QoL for his youtubing which went on hiatus some years ago for personal reasons.
It was designed so that all the little triangle warnings would me less intrusive while he was building - usually unpowered.
So that chunk of code is the 1.1 way of making the blue triangle notification that modules are needed but not present less annoying.
Since 2.x changes how that is displayed, it makes sense that it errors out. Not sure if it is really needed, as the module warnings are actually less annoying in 2.x and are informative.
My OP was basically wondering if you were planning on implementing it or not.
