    • Adjusted the way 'Mechs fire weapons in a weapon group. If a target is low health and a weapon group is selected to fire, it will only shoot the number of weapons it needs to destroy the target.

    • Arena Master trait now properly gives bonuses to Rifles, PPC-X, Binary Lasers, Chem Lasers and SRMs.
    • Fixed a bug where some traits were only applying to one weapon in their list.
    • Autocannon Master traits now apply to all ACs/LBXs/UACs in their class (ie, AC/10 Master now applies to AC/10s, LBX10s, and UAC/10s, including variants.)

  • DLC7: Shadow of Kerensky Campaign
    • The Shadow of Kerensky campaign has been altered. Now requiring players to complete the sandbox portion of the campaign within a fixed amount of time. (To guarantee campaign completion before the events of Chaos Reign)
    • Failing to complete the sandbox portion of the campaign within this timeframe will now result in an automatic abandonment of the Shadow of Kerensky Campaign
    • New transmissions alerting players to this behavior and periodic reminders that they are on the clock have been added.
    • Previous saves that have triggered or entered the final act of the Shadow of Kerensky campaign will be allowed to play through the remainder of Shadow of Kerensky regardless of newly implemented time restrictions. But they will be unable to accept the Chaos Reign priority mission unless they complete or abandon the Shadow of Kerensky campaign before the Priority transmissions' expiry date.

(Design Notes) With the Chaos Reign campaign being a direct continuation of the events of Shadow of Kerensky, it was important for us to maintain internal continuity in the game's story and avoid errors that could arise from overlapping fixed quests.
