soasertus, that little tip makes sense, and I will try that before going any further. I think a lot has to do with all the new windows and such, and new research and abilities. They all deal with new or edited graphic files from what I have found that Entrenchment changed. Also I still need to flip all the channels of the ship textures to the new format, so that may also have something to do with it.
More good new is that it is now partially working, as I have a "base" mod now going, with new explosions, weapon effects, music, and dynamic ship movement, so that the ships move around during combat.
Either way, I WILL figure this out, and will have something to release soon to you all, as I know you are all waiting. Thanks for being so patient.
And yeah guys, 2.1 only works for 1.05 version of Sins. The next version will be for Entrenchment, which is what I am working on now.
More to come!
