Coop - Karax healing beam gets stuck

Definitelly a weird bug, never seen this bug like ever and I do play Karax a lot, this happened today.

Here’s the replay:

I believe it was around 14 mins into the game?

In this match I was mengsk, playing on hard, pretty chill match since we both was doing okay-ish at macro(not perfect by far but well, back to the bug report), as I dealt with attack wave, the medivac was stuck on 145 health with beam, just 5 points away from full health.

Once I used worker to heal back to full, then bug stopped and I just went to play normally.

same thing happened to me i believe.
