This same exact thing is happening to me, hope someone can give us a hand.

I solved it. I have seen some people commenting in forums about answering wrong in purpose 1, 2 or 3 times before answering right. That didnt woked for me.
The solution was to lower the PhysiX acceleration to low, answering the riddle and when u get a new save game u can go to main menu and change it back to high (or wherevere it was before) and keep playing.

I have same issue, will try the suggestion, Thanks

Confirmed works! Thanks Darth

Thanks

worked ;)

Worked for me, thanks :D

just got the same problem gonna try

Worked, thanks!

Also works for origin version :)

I can confirm that switching the PhysiX to low, and switching it back once you have exited the Radula, fixes the issue. Thank you @Darth_SHAKER
