EOS bugging out

Continuing the discussion from EOS randomly restored his health, shield and torrents:

so this same thing happened again but he disappeared for like 5 mins and left me with a few badass viruses. the third time he didnt even heal his health, he just disappeared and didnt come back

I’ve had so many buggy things at this fight, including him disappearing. Worst is the crashing after he drops his loot (happened 4 times already)! Pictures of an orange drop on my screen as I have to hard quit to restart my PS3 – not fair!
