When I got all the DLCs and upgraded to NVSE 2b9 my Readius stopped working, so I modified it until it worked. This is a modified esp for the New Vegas Readius mod that seems to be working (at least for me and a few others) in 1.4.0.525 as well as with NVSE 2b9 (both current). This is only a patch, so only the file changed (the esp file) is included. Please download the official posted Readius from the below link and replace the esp from there with this if you are having issues getting the Readius to recognize NVSE ingame. If your Readius works already this patch shouldn't be needed.

I verified this works on new and existing saves on my system, however as I don't know what I'm doing with the ESP files it is possible there is a better/easier way of doing this, if you can, please do.

I am only posting this to get another mod working with this patch & am not claiming any credit for the mod, if you like the Readius go and Endorse at the below two links.

I edited some of the code in TESsnip in the FOMM and replaced all mentions of the fose with nvse.
I changed "elseif (NVSEVersion 0 && NVSEBeta 1)" to reflect the raise in main version, not just subversion.
I also changed the "setStage BIDEpipNVSECheck 1" to =0 as it would not recognize the new NVSE any other way I tried.

If I messed up the code somehow feel free to fix as needed to get this released back to the users. I spent the time to find a fix as this is a mod that is a must have for me =)

Legal Info
Noticed in the Fallout 3 Version that there is the following link to a post from AlexScorpion that the original mod is considered a free resource for modders.
I contacted Brianide & waited over a month for a response before posting this, so followed what Brianide asked as well.

Per the original Legal listed...
You must contact AlexScorpion before repackaging any part of this mod. If you do not receive a response within two weeks, feel free to do whatever you like with this mod, so long as its authors receive proper attribution.
Contact Brianide for inquiries concerning the script.

As for my wishes, I would like to see this mod stay active, and I don't know if I'm the best to do it, so the only contact I can see that a potential modder will need to make for alteration and posting is Brianide, not me.
