Lingering illusion not working in kulemak invititation and boss totally invisible

Bug Report ID: #1558708458

vessel was only visible in first phase, every subsequent including "full fight" he was completly invisible, had to find him by aoe attacks being unable to deal with the encounter normally.

Also lingering illusion did not work here, no illusion created and was unable to generate power charges due to this. Tried toggling on and off, did nothing.
