Transformation Issues

I have a building an "ancient' classification.

It has an ability which transforms it into a non building unit.
It all works fine until the point where the unit transforms back into a structure.

When that hapens the building form becomes invisible but still leaves a shadow.

- The transform is based on Bear Form ability.
- Both the unit and the structure are identical except one has the "Is a building" field set to false.
- Both are ancients
- The unit form is mobile the building form is not.

Funny, I tested the exact same thing while working out a moving shop except mine crashes the game instead but it can do it fine between both until it does crash. Tried using root instead?

I managed to solve the problem by triggering the whole event.
so nvm.
