Bug with scheme/diagram

[a909a]

fix scheme where the towers are shown
because the longest bars in this diagram are shown incorrectly.

on the replay:
if the midboss is dropped by opponents - the WHITE bar drops
if the allies drop - the RED bar drops

in the real game:
if the midboss is dropped by opponents - the RED bar drops
if the allies drop - the RED bar drops

WHY? can u fix this scheme/diagram

im about this diagram on the screenshot

And I assume that if the allies dropped the midboss before the enemies, then the WHITE bar will never disappear.

And if the enemies drop the midboss (the white bar disappears), then after a while the allies drop the midboss (the red bar disappears)

I dropped a midboss in a sandbox and the RED bar disappeared

I went to a player's stream, they dropped a midboss and the WHITE bar disappeared

Why is that?
