Not sure if anyone else has this problem, or if it has been addressed before so I will elaborate.
My current project uses about 5 custom dependencies, all which are nearly filled to the maximum capacity with custom models/images/sounds. It seems that every time I go to load my map either 1, 2, 3, 4, or maybe even all 5 dependencies won't load on the initial start up of the map and causes an error and asks to proceed anyways. Obviously if I proceeded anyways there wouldn't be any custom items in the map anymore, now would there? Though it is easily fixed by restarting the map I still see this as a constant hassle and it needs to be addressed.
