If a barracks tower has an upgrade with multiple levels and you upgrade said upgrade multiple times while the units are moving, the units only receive one upgrade. The same applies when the upgrade is upgraded multiple times in the same frame.
When the units die and respawn, the stats/abilities are correct.
