Thanks a lot for your patience and help.
I did go through the links you mentioned.
Ok, so I am planning to remove my current modded BGII SOA folder and restore my old unmodded but TOB, bonus merchant patched one.
Then I am going to re-install all the mods (including RR this time

), skip ease-of-use mod, and then install the G3 tweaks in the end (or do you suggest putting the G3 tweaks before RR??). I am planning on skipping redemption this time as I dont want to risk any serious bugs when I am about to finish TOB (as you said RR was not tested with redemption).
Thanks again for your help
