That's what I have... 3 upgrades are completely identical. Who would be interested in this? And the Destroyers were imported from the seventh game...
It should be noted that minor visual changes are only visible on the purchase screen and when examining the unit in more detail; they are hardly noticeable in battle or on the map, mainly in terms of color. We wanted to add fire and smoke to the upgrade and alt-upgrade, respectively, but we haven't been able to do so yet for technical reasons.
Also, dear kolt_av, it's quite easy to write sarcastic comments rather than suggest fixes for the nuances that personally bother you. Those who are interested will download it.
И пусть Эльрат осветит твой путь
