Thank you very much, guys, for your quick replies. And I'll answer. You may find it funny, but I've never done this thing before. Well, I suppose, there's always something new to try in your life... any guides or tips about that? Yeah, though it could have been that I haven't noticed something important. Oh... yes, my bad. Even if activated is just Natural Weather corrected by Ryu Doppler, along with All Natural - still, I admit. A mistake from my person. Well... yeah. But maybe that is a result of installing the mods with OBMM Extended (it did asked me some installation options during mod installing)... Which also leads to another part of your post, where you've mentioned OBMM/Wrye Bash. Using them both, though TBH, I've never used WB to install a single mod. Preferred OBMM. Also, got TesModManager for Oblivion, but something tells me that it may not be the tool I need to use. Wow, thank you very much - I honestly did not know that! My answer is a bit silly/stupid, but I haven't encountered any serious bugs while playing Oblivion. Maybe there was a two-three of them in the past, but not now. If UOP must be used with mods - did not know that. Will use in the future. So, if I understood things correctly - must reinstall Oblivion with SI and KotN + other official plugins, patch them with official patches and UOP as well, then install other mods one by one (excluding Weather Natural and some others) with WB/OBMM. Right? Then use WB to build a Bashed Patch... BTW, are there any settings in building a patch that I have missed? And then - LOOT/BOSS. Also, is there a particular order which mod to install first, then second then etc and etc?
