Ok...So heres the bottom line. I am making a faction and I have 1 craft, 1 soldier, 1 brain and various weapons, explosives and tools. I have been working on the soldier and changing up the sprites. One day I start up CC to test my soldier and I can't find him in the pregame menu or in the ingame menu.
Earlier today I went into the code and put Buyable = 1 into the actors code. I started up CC again and I still can't find him anywhere on the menus. Help is gravely needed for my mod production to continue.

Is it on a new or at least clean install, have you included the files in your index, and is the .rte set up correctly?
If you answered yes to all of these, you might have to move the files somewhere else, (ie move the .rte contents to a new folder, delete the old folder, and then rename the new folder to what the .rte was.)
A good giveaway is to write something blatantly wrong eg ERROR somewhere in the .inis that are giving you trouble to see if the game is actually parsing them.

Do you have the AddToGroup = Actors or whatever?
Do you have it loading the actors ini file?
Check these.

@ Geti: I made a new folder and put the old contents in it and put blatantly wrong code in an explosive and CC started up.

@Joesy: All the Indexes are working fine but apparently not being read for some reason. All of the AddToGroups are there.

I had this problem too when my actor had the same name as another existing actor

If the error code isnt causing a crash the files aren't being read. It's possible they're corrupt (though that usually just causes a crash) or your .rte is ghosting for some reason. try the copy everything elsewhere routine.

Oh man! alright...
Is there anyway to keep this from happening in the future?

It shouldn't take long, you literally have to make a new folder (right click>New Folder), and then go to your .rte and cut everything, and go to the new folder and paste everything (ctrl+x and ctrl+v respectively, just in case ). After that, just delete the empty .rte folder and rename the new folder to the .rte
Usually, this is just a zip indexing error, but it's possible for it to happen otherwise. If there's corruption, it usually causes a crash.
Oh, also, make sure you dont have tabbing in the other subindexes in your mod (like actors.ini or whatever) on the includefile lines, as this causes things to not get read (in my experience).
ie
rather than

Ok. Ive replaced the main folder twice now and I completely copied and pasted one of my soldiers and he still doesn't show up.
I have a hunch this is going to lead to complete remakings of my soldiers. (Plz NO!)

post the .rte, i have a feeling it has to do with tab syntax.

Heres the .rte in .zip form.

Apparently it looks like you may have commented it out.

Or at least, thats how i see it.

Make sure this isn't the case. I had this exact same problem before.

@ Dragon: I don't see any included files commented out only the word Devices.
@ Linkfan: All of my current actors have different names.

try deleting the commented out words.
