I modified infantry and vehicle units to stay after death in Kane's Wrath, using WrathEd.

All I changed was SinkDelay and DestructionDelay
While it seems to work in-game, somehow all of the units have no voices (when you click on them or issue them some orders, they don't tell anything)

I'm going to describe exactly what I did, just to be sure.
For example, the NOD militant unit.
I made a NODMilitant.xml file, where I copied everything from the original one, from




to




and the only 2 things I edited are the SinkDelay and DestructionDelay parametres.

So, can anyone help me here? What is wrong? Why all of the edited units have no voices?

If this happens, go back and make sure that your units are not using any mod units (which would just give them a voice) and then try again. If you use the same unit multiple times, they should not have duplicate names. In addition, if you have duplicates, make sure they're actually different from each other.
