I'm having problems with my fallout Im running about 30-40 mods in my game most of them small mods nothing big but when I try to install another mod doesn't matter what my game acts up texture go missing when I load a new cell pipboy displays purple block instead of weapon icon and any menu is messed up like merchant inventory and I've tried everything to fix it but in not very adept at it any help would be much appreciated cause I'm out of ideas

how do you install your mods?

Have been reactivating archive invalidation? Whats your graphics card? are you using a ENB?

I dont know why but it seems like every one have a diffrent plugin limit,seems like yours is 40.

Try to merge them this helped me a lot

It would really help if you could post your load order here and give more details to help troubleshoot your problem. Other than that, have you made sure that archive invalidation in activated? Did you make sure that there aren't any conflicting mods which modifies the same files? Did you install the mods properly and made sure all the required texture and meshes are properly placed in the data folder? Did you accidentally delete or overwrite an important texture or meshes?

We can't really help you without sufficient details. Maybe you should try running (are you running fallout 3 or fallout nw) FNVEdit to see if there are any problems with your load order. You can also identify which mods overwrites which as a conflict winner. The UI being messed up is usually caused by a problem in the hud_main_menu.xml file. Have you made sure that you properly installed your UI mods? Thats all that i can think of right now. Hope it helps

Right forgot about details first I'm using Fomn to install my mods and I have no enbs I use archive invalidation invalidated and I have an nvidia GeForce 760 graphics card maybe it could be that I have to go fnv edit to fix the problem but I'll have to look up how to use it on you tube cause I'm not very adept in such matters thanks to everyone who responded I appreciate it it helped me get one step closer to solving the problem

if it will help my cause here is my load order if anyone could point me in the right direction it would be greatly appreciated

If you use all of these mods then your load order limit is reached,only merging would help.

ok so it would seem my next question how do you merge the files could you help me out by explaining or could you link a youtube video to help me out it would be greatly appreciated

You might find this video helpful: https://www.youtube.com/watch?v=qVKe51dRm2M . Skip to about 2:45 when Gopher starts talking about FNVEdit.

You might want to install this mod over your FNVEdit installation: http://www.nexusmods.com/skyrim/mods/37981/? . I got this information from Essarrbee's STEP guide, found here: http://wiki.step-project.com/User:EssArrBee/FalloutNewVegas

Yes, I second TinyWaterbear with Gopher's video. It's what I myself used to learn about FNVEdit and boy has it done wonders for me ever since.

Another thing that might help you is 4GB New Vegas. http://www.nexusmods.com/newvegas/mods/55061/?
