hello, i made my own custom sides mod, and well everything worked fine, that is, until i made a new version with released assets, such as the T-21, added into it, and hence, i get i CTD every time , might someone be of assistance?

If you havent already. Run SPTest.exe and look at the bfront.log that it generates

thanks for the reply i tried, but it crashes before it can even work

Look at the bfront.log that appears below it and it will tell you your errors

thank you, however the thing is, it seems that it crashes before the bfront.log is made, as the bfront.log is no where to be found, perhaps its where i have the SP test exe?

The BFlog is prolly there but you have the press the "compatability files" button below the folder path.
