Oh well, that may be true, I also did it only once recently before uploading my latest Halloween pack. I had an issue with one model having higher health bar, and read somewhere that I should reduce height or some number in sequence. I did it and it worked actually, I lowered number and health bar was lower. Just setting extends in Magos or MDLvis did not work, but in sequence editor it worked. But again, cant confirm what I did because I did it only once in my life, but I remember it worked. Now, I understand that Town Hall structure system is a bit complicated than single unit model, and can be difficult to achieve.
