Altered Destroyer Form ends in game crash.

I'm making this cinematic, where this sky-barge-ish ship is coming out of a huge portal, and I encountered an issue. Since the portal is quite low and the barge flies somewhat high, I needed to work a little to make it look like it's coming out of the portal. I tried the following:

-Making two similar looking units where the first has ground movement, and the second is the flying vessel I will want to use. Then alter the Destroyer Form ability for the first to "morph" into the latter. It actually works you can see it does the "lift off", when.... CRASH¤%&/.

The game crashes. Can any of you think of why this happens?

Why not just use a trigger to change the flying height of the unit?

there is many limitations on shapeshift, to evoid crush make alternate version of unit by copying original, also set dependance field.

I'm not sure about destroyer form but when using storm crow form there are a few things to pay attention at:
-Check the data fields for normal and alternate unit shape.
-Give both units that ability. The normal and alternate unit.
-Don't morph heroes into normal units or vice versa.

Choose wisely!

That would be the best, of course, but I don't see a function that manipulates that property using the normal WE.




That's it!!! Awesome!!
