I've been experiencing many problems with the mod right now. I believe this is because I am unable to install C.A.L due to its discontinuation. The most common problem is that the nukes don't explode like they should, all I see are the stock explosions, the other problem is that some of the mod textures just aren't there. Some parts are all black when they shouldn't be and some nukes (Fat Man is one of these) are completely grey. I am using KSP 1.3.1 and have the updated NKD and BDAc. I installed these with CKAN and made sure they were in the GameData folder and had the correct name.
