Hi Androo,
Nice to meet you.
No, you shouldn't need a patch. Gold should be all set up for mission building. You probably have a typo or other procedural thing wrong in how you did your setup of files and mission folder. I put together a little tutorial which might help.
Step#1
In the main Enigma game folder, look for a file called "localization.txt". Open it in a text editor and add the green highlighted line below the "Tactical" line. The word "Custom" will be what you see in the game dropdown box below "Tactical". Resave the file.
Those are not spaces you see in the line you just typed (like between the words TOGGLE and Custom). They are tabs. Be sure to tab between fields (1 tab), DO NOT use the spacebar or it won't work. Enigma uses the tab to delimit fields, so use the tab key always.
Step#2
In the game's \missions folder, open the "index.pkg" file into a text editor. Add the green highlighted line after the "RandomPatrols" line. It becomes our 4th player package. "CustomPatrols" will become our folder name where we will keep our missions. Note that they are numbered 0,1,2,3, etc. On the "Single Player Package" line at the top, change the 3 to a 4 since we now have 4 player packages. Resave the file.
Step#3
Now we will create the .CGN file from scratch. The .CGN file is like a mission directory. The picture example is my .CGN file, which has 9 missions in the directory. Open the text editor. Type the first line like is highlighted in green and red, except instead of the red 9, make it a 1 (one) since you will have one mission to start. On line 2 (the ML line), type your mission line, substituting your mission name in place of "Docking Practice". Note that in this case there is a single space (not a tab) between "Docking" and "Practice", since it is one field, the name field. In place of the word "Description", you can type a simple phrase describing your mission. Now, save the .CGN file into the \missions folder using the name "CustomPatrols.cgn".
Step#4 (no picture)
In the same \missions folder, create a new "CustomPatrols" subfolder. Open this CustomPatrols folder. Copy your missions (.EMS file(s)) there. Name them in order, mission-1.ems, mission-2.ems, etc.
You're ready to go!
In game, be sure when you click the dropdown list to look for "Custom" underneath "Tactical" missions, you scroll down with the scrollbar. The dropdown box only shows three lines at a time and it's easy to miss anything underneath the top three lines.
Have fun!
