The slavers quest can cause a CTD if you choose to hire Daxus and have him fight his former employers. As soon as the tactical combat starts loading, the CTD will occur.
- Start Slavers Quest
- Choose to Hire Daxus
- Choose to Kill the slavers
- --- CRASH ---
I have tried all the other paths in the slavers quest (killing Daxus and slavers) --- they all work fine.
