Main screen options not loading on startup issue

[Derialund]

Hi, I would like to ask you if there's a way to understand why the in-game main screen options doesn't show when I launch the game. The game simply hang, with the music playing. I have made a merge mod and I have found out it is causing this issue, but I would like to know if there's a way to understand where the game exacly stops from loading, considering that checking the mod with FNVEdit, doesn't report any error present on the .esp file.

Thank you for the answers.

"User Interface (UI)" problems indicate you have changed XML files. This is often caused by an "install order" problem with more than one mod replacing or editing the same XML file. Please see the wiki "HUD-UI-Menu issues" article. (This takes some interpretation as applies to your situation. There are too many permutations for an "if A then B" type of guide. If you haven't encountered XML files before then the "TL;DR" section is not going to help by itself.)

"Disabling" mods is not enough to restore things to "vanilla" if they overwrote any files. UI mods definitely do this, and can make "edits" to other existing XML files. You have to "verify local files" to restore the originals, and still may need to delete the "loose files" so those vanilla versions get used from the BSA files. Then correct the sequence in which you install those UI affecting mods. Please see the 'Restoring to "Vanilla"' entry of the wiki "FNV General Mod Use Advice" article.

Please provide ALL the information requested in the wiki "How to ask for help" article. Don't forget to identify things that do not appear in the "load order", such as the version of Windows, if you are using a "Steam" or "GOG" and/or "regional language version" of the game (even if you are playing it in English); using the FNV4GB Patch, NVSE and it's related plugins; replacements for textures (specifically their larger image sizes: 1024x1024, etc.), animations, or "bodies", etc.; and "post-processors" like ENB or SweetFX. It saves us playing "20 questions" and gets you a more specific answer more quickly. (The usual turn-around on post and reply in an older game forum is 24 hours.) Screenshots of the "load order" don't usually work so well because they tend to cut off or fail to display needed information and are hard to "piece together" into a complete and coherent picture.

* See "How to markup images (etc) in forum posts and comments" article for how to use "Spoiler tags", etc. "LOOT" already includes those tags in the "load order" it copies to your clipboard, so you can just paste it's list into your post.

In the meantime, please see the 'Vanilla Load Order' entry in the 'First Timer Advice' section; as well as the 'Towards Game Stability' and the 'Common Game Problems' sections of the wiki "FNV General Mod Use Advice" article.

If the problem persists, then work through either the 'Solutions to Starting the game problems' or the 'Solutions to "Crash To Desktop" (CTD) problems' sections in the wiki "Fallout NV Mod Conflict Troubleshooting" guide.

I recommend anyone read the entire "FNV General Mod Use Advice" article to understand the differences between this game and others you may have experience with; especially if this is your first attempt to play a modded FNV or it's been more than a year since you last set it up. It is designed for someone who has never played a modded PC game before, so it tries to avoid making any assumptions, is kept "up-to-date", and covers years of "lessons learned" by a retired Technical Support expert. It is NOT a list of various mods to install that happen to work on the author's machine; only "the essentials". It addresses fundamentals underlying how to get the basic game and mods to work together. At least 90% of everything I post in the "Technical Support" sub-forum is already in that article. Once you can play a test game to at least Primm, only then should you try adding other mods from some other "guide".
