If duing morphing a unit(in my test's with a cellmap) into a larger unit (with a larger cellmap).
[incomplete text
Advanced but very precise explanation
When a unit(unit A) morphs it first check's if the cell map is clear for the unit it morphs into(unit B).
As long as the unit that are morphing have the same size/cellmap size(unit A) as the unit it is morphing into (unit B) there is no problem.
However if unit B have a larger cellmap than unit A it's goint to be a problem.

The unit will not occipy the entire cellmap while morphing, wich means that other units can walk into the morphing area and this canceling the unit morphing this is especially annoying with unit's wich have a long build time until to see a unit standing inside the now not-morping unit. Because it finsished but did not have space to finish. It is also problematic whe you have serveral units morphing because if you have them too close they will start morphing because there is enough space but only some of them will finish because the finished unit size is larger than the base unit.
