Bug with Garuda Hardmode Unable to target invisible boss

[kenji815]

I been experience in multiple times not being able to target Garuda in hard mode.
I took screen shot showing problem.
Garuda would become invisible on my screen (still show garuda on enemy list)
and i would be unable to target the boss (invalid target)
i don't know if this is a latency issue or what?
Garuda would reappear when she warps.Usually she disappears during 1st half of the fight.
