I'm seeing something strange with v2.0 (maybe it was the same with previous version, I don't know).
It seems to break the demson.dlg file. Mods that I install after sod2bg2_iu that also try to modify this file all fail ("can't verify the action").
If understand correctly; this mod does this:
COPY_EXISTING ~demson.dlg~ ~override~
REPLACE_TEXTUALLY ~plat15~ ~dtkrnd04~ //Mail of the Hallowed Hero +3/Pride of the Legion +2
This might work in all other files which are ".d", but this one is a ".dlg" which if I'm not wrong is a binary file.
And as you just replace 6 bytes with 8 bytes, this might not work totally as expected.
When I inspect the resource with NearInfinity, before install sod2bg2_ui, I see
SetGlobal("PaladinPlot","GLOBAL",60)
GiveItemCreate("dtkrnd04",Player1,0,0,0)
GiveItemCreate("shld30",Player1,0,0,0)
ActionOverride(Player1,RegainPaladinHood())
After installing, I see
Notice the two unclosed parenthesis(es?) and the red error image.
EDIT: you can take everything I wrote with a grain of salt, I know next to nothing about IE resources or weidu.
