I also have problems with the combine_files, but i have a different problem.
Look at this code snippet
if((Director::isDev() && !SapphireTest::is_running_test()) || !Requirements::get_combined_files_enabled()) {
return;
}
Either i'm to tired to think or it will just return if we are in dev mode and this is not a test?
Anyhow, since i'm using dev mode and is_running_test returns false the rest of the function is'nt run, or are there something i have missed?
