Jorgin and Spider build - Rference Number 38 068 804

This only happens with Jorgin.

Everytime i have to fight him, the spiders keep attackin the poor man indefinitely until i pick an option.

Hello there.

I can confirm that.
Jorgin often continues to be handled as a valid target once defeated.
Also, most of the time, his exotic effects (granted by syndicate items) are generated until you actually select an option, though the damage they provide isn't processed.
That bug has been there for quite some time now, and is specific to Jorgin.
