Custom 'Call to Arms' ability -- worker cannot build after going Back to Work?

[PiesOfNorth]

I've been experimenting with Call to Arms. I have tried to make Mur'gul Slaves have a custom Call to Arms ability that turns them into Mur'gul Reavers. The unit transformation back and forth appears to work correctly, but the Mur'gul slave is not able to build after he returns from being a Reaver.

To be clear, the build button is still there, and you can give the order to build a structure, but once he gets there to start building, he just sits there instead without doing anything.

I can't figure any reason why this might be. He can build just fine before the Call to Arms, so I'm guessing it's not something I broke in the Slave unit. Anyone have any ideas?

Make sure that the Mur'gul Reaver can also build those structures.

Huh, hadn't thought of that. Works now, thanks!
