I would suggest one tip to all people having problems with components included in other mods. First of all, however, I will give my opinion about the "root" problem which has caused all these problems: the multifunctional mod concept.
The problem arrives when putting into the same package two or more independent components being one or more of them not referenced, but original content. ISI made a very nice multifunctional mod concept but did not provide suffcient information of how to use this tool. From the beginning the "referenced component concept" was implemented (some mods referenced circuits installed with other mods). However, ISI failed to correctly use it and started provoking all this mesh: The released huge size mods with more than one track and vehicles in the same package. How should have it done? Releasing independent mods for vehicles without any referenced or fully included track in them and with tracks as independent components and afterwards explaining how to create a virtual mod to play online/offline.
Now, instead of doing things the right way, they have invented a new concept, the "multicomponent mod" which in my opinion does not provide any improvement since things could be done correctly with previous tools without the need to complicate evrything more with a new unnecessary entity. Now let's go with the tip...
TIP
I have succesfully managed to independently install a component (vehicle in this case) which was included in a mod that referenced a track that was included in another mod. Someone will think it is a tongue-twister but no. Actually, I am talking about installing Nissan 370Z without having to install and update the required mods to get the required 4 tracks. At least FR3.5 is required and I am not sure if additional mods are required as well. The new mod manager is for sure nicer but still does not provide a essential info to help users identifying the original components:
PLEASE ISI INDICATE IF A COMPONENT IS INCLUDED OR REFERENCED. Actually there are two ways to proceed to "create independent component" packages.
1)
Let's call it "the clean way": Create a new mod including just a component (not referenced). If done with a track or a vehicle, the equivalent to a rfcmp component would be achieved. For sure, this needs to be done by someone that has the component installed before other people can use it. It is quite useful to organize league online competitions and ease the downloading/installing procedure for beginners.
Example: This mod installs the Nissan 370Z but requires having since it was as independent component Pocoyo 1.05

2)
Let's call it "the hacker way": Make a zip file with the same folder structure that is used within the "installed subfolder" within rf2 root directory. For a track you just need to copy the locations folder and the track subfolder. For a "vehicle multicomponent",vehicle, sounds and talent are required. As before, this zip file needs to be prepared by someone having the component installed.
For example this file
https://dl.dropbox.com/u/6587895/Installed.7z insatalls as well the Nissan but without going through mod manager. You need to unzip it in rf2 root folder (where your installed folder is)
MY WISH. Everything would be much nicer if components could be extracted from a mod package into a new rfcmp for tracks. For vehicles I guess the first option I present is the way to create a multicomponent mod so nothing would be really required.
