SWTOR bug Scratch the surface

I seem to be unable to submit the bug neither in-game nor on forum, so will at least try here.

In the Scratch the surface quest on planet Quesh when you enter the Sewage treatment level you have to gather sewer fruits and throw them at consoles, so that sewer lurkers will crush the consoles. It worked for me on the first console. On the second I gathered the fruit, thrown it - then nothing. There are no more fruits, console is inactive, the lurker just stands where it stood. The gate is closed. 

I tried reloading several times - still everything is the same. I can not progress the quest line.
