Beware of possible spoilers below:

Patch notes:

• Abelard could become missing in Commorragh if the Lex Imperialis expansion was activated in Act III. Fixed, let's not have the dear senechal suffer even more!
  
• If the first Abelard's quest was failed or skipped, it was impossible to start the expansion content from a save in Act 4 due to the lack of the quest NPC - fixed;
  
• For the first arena of Commorragh, it was possible to get 3 companions if Solomorne, Abelard and Argenta were in the party - fixed, Abelard will come after the first arena in this case;
