Also a bug of 177/178p1 which will be fixed with the next release. Actually its already fixed with a internal development version.
And it only happens if "AC.setCustomGodraysColor()" isnt used in the ppfilter script, so its not really a bug. But it will be fixed anyways.
Working fine for example with the ppf PureLife-Evo-GT which I currently use in combination with Pure. The ppf could work with SOL too, never tested it tho.
