I don't play with many mods so it's strange that it doesn't produce a final save. Apart from EET, I only install SCS, RR, adalons blood and some options from atweaks, as well as some random UI mods and original BGI movies...
I fixed the XP problem by removing XPBONUS.2da from override, I don't know why BGT insists on putting that in there, it seems redundant and isn't provided as an option anywhere.
