ULTRAMARIO Engine troubles, Random sounds are randomly muting.

I'm using Ultramario's Wario Land engine for a game right now, as well as his famous M&L platforming engine for another game, but I've run into some trouble. While working on the games, (the same thing happened with both engines) I noticed that several sounds weren't playing in the executable. I deleted those sounds and replaced them, but found that a set of different sounds weren't playing, instead. I don't want to delete and replace every sound in the engine, so can anyone help me out?

Um, could you please tell us where we would find this engine? Also, please change the title to "UM Wario engine" cause I thought this was about UME, not his wario engine.

These engines are really easy to find.

I think he wrote both in D&D, so if you delete a sound, it loses it´s index. An index is given at the creation of every resource, you have to go into the events and search for actions saying "Play sound <undefined>", that´s the result of deleting a resource. In code, that problem doesn´t ecist since there only the Names count.

Hold the phone; I ran both games today and the sounds are working again. Hmm.

Well, I'll post back here if I run into the problem again.
