I have a BIG Problem with the indicator compiler MT4 build 220 decides to compile most of my indicators but not all of them,and I don't know why??

 
Sometimes when I compile a new custom indicator, MT4 decides to compile most of my indicators but not all of them. Some of my custom indicators do NOT appear in the Navigator window when this happens so I can't drag them onto a chart. Do anyone have any idea why this may happen?I have more than 500 custom indicators that I use.Please help me with this problem.
 

All of them are probably compiled, unless there are compiler errors... which you can easily see.

However there may be dependancy problems, some indicators rely on (call) other indicators, and if

these other indicators did compile with errors, or do not exist the indicator may not work. But it

in case of dependancy problems the indicator should still appear in the navigator, and it should be

possible to attach it to the chart. ALWAYS restart MT4 after compiling new indicators!
