Building Moves when replaced

[Vibon]

I have a unit that can build a building (And you can walk on the building - Patching map - Ruined Ground (4x3)). That building can create 1 unit, and when the unit is finished training, the building is replaced with another building.
But the problem is that, when i use the trigger to replace the building with another, then the building is moved because of thee unit who stand on it.

Anyone who got an idea for this not to happend? Any tips or tricks?
EDIT: UPLOADED SCREENSHOTS.

SOLVED
- Added Chaos Ability to the unit.

Instead of building another building why no use the Upgrade tool? the same way human towers can upgrade

Hmm, i dont think thats work, becouse, when im finishing training a unit, a trigger replaces the unit, and i dont think the upgrade work with triggers.

This is the trigger, very simple:

Trained Unit
Events
Unit - A unit Finishes training a unit
Conditions
(Unit-type of (Trained unit)) Equal to Zombie - Unit 1
Actions
Unit - Replace (Triggering unit) with a Soil using The old unit's life and mana

Try setting the building pathing to 0/none.

In the custom box, just type "_" (Without quotes).

It will be a problem, then im able to build buildings on top of each other, and thats a problem.

change patching to 1 to 30
but you have another easy way

Instead of building another building why no use the Upgrade tool? the same way human towers can upgrade

or when finish training, use remove training unit and create unit at place of training unit

Is there a trigger to force that upgrade?

There is a trigger action: Player - Set Current Research Level. Or you could add a Chaos-based ability to the building, i.e. the unit abilities under Orc that change unit-types directly.

KaerfNome, you got the answer, thank you, it works as it should with the Chaos Ability!
