For example, I don't like the orange sinuous ribbon that appears in the left side of the original screen, but I like que metal-like thing where the medallion and the status bars are shown. If you get a DDS viewer you can also investigate into the RotWW folder, and keep some GUI parts that you like. If you do, you will notice that, for example, the 'ui_stlswd_001' file in RotWW shows an image, but the one in EI is empty, and I think that's why it disappears in the game when you install Extreme Immersion. If you want to see the content that you are deleting, download a DDS viewer.
Try deleting the files in the RotWW GUI folder that are named the same way that the ones in the EI folder. I deleted the DDS file named 'ui_stlswd_001' in the RotWW GUI folder and the Steel Witcher Sword disappeared, so I think that must be the answer. So, I think that the game must be loading the RotWW ones later, giving them more priority. I noticed that inside the GUI folder of RotWW, in the Data directory that's inside the game directory, there are some DDS archives with the same name of the ones that are inside the EI folder. I installed EI a minute ago, and had the same issue, with the weapons, potions and other icons showing. I never used the Extreme Immersion Mod, but I use the Rise of the White Wolf, and know a bit about it. First of all, I'm no specialist, but perhaps this helps you.
