Try redownload avalon included RCIHPLOPALL here. Actually from last yayie's update 21st AUG 2014. http://www8.zippysha...54775/file.html I downloaded from your link (which tried to add a malicious program to my computer, just so you know), and I replaced the files, and it did nothing, because according to Yayie you need AllRCIPlop 2.0 which I don't have and is the file I'm looking for.
I've carefully read through this page multiple times (and downloaded and installed multiple times the latest files) for the last 3 days, but I cannot plop down a single building. After much investigation on the comments here, I realized I was missing a file... AllRCIPlop 2.0. However, this file is not included in the Avalon file. And I can't seem to find it anywhere on the site. Can someone please send me a link to this file? Much appreciated. And to be clear, this is the first time I've modded SimCity 2013, so I don't have any old files, etc. And I double checked to be sure I don't have any conflicting mods.
