hmmm...not that I doubt you, we might afteral be looking at different versions here, but never having noticed any probs or things that should have been different, I just now took a quick look in both vp files...I honestly do not see where there could be any conflict?
Here's what I have in these files (btw, I
did rename sparkee_fs2.vp, but I used the same naming scheme as used in fs2 and renamed it to sparky_hi_fs1.vp which I thought far more fitting

. )
my sparkee_fs2.vp has 31 interface art files in it, all names starting with 2_
among all the files in my fsport2_3.vp there's only
2 !! files in it with names starting with 2_ and both are for files not even present in sparkee_fs2.vp, so according to how fs locates files, there is IMO no problem ???
fsport2_3.vp 29,233,116 bytes
sparkee_fs2.vp 40,177,130 bytes
Different version ???
