put it this way... many many people have reported problems with SP when having all the mutators on and all mods enabled... some mods do conflict with SP, while some can work perfectly fine through the entire campaign... no one has really ever gone through testing each mod one by one through the campaign to determine which ones will work just fine and which ones will not; that would take a while and many times playing through the campaign beginning to end lol
the general reply is to just have them all turned off...
anyway, to go back ontopic, BR is fixing whatever problems may be with his pack and will no doubt rerelease it whenever he can... there is a temporary fix, which has been mentioned in the meantime...
