Q: Is v1.51 the final planned update for JA3?
A: No. Haemimont Games has confirmed a major DLC expansion is in the works for Q1 2024. v1.51 is the "foundation patch" for that DLC.
Q: Will my save file from v1.50 work on v1.51?
A: Yes, but with minor issues. You may notice that some of your mercenaries' perks have been reset, and mine income might fluctuate. Back up your saves before updating.
Q: Why is the GOG version smaller than the Steam version?
A: The Steam version includes redundant DirectX and VC++ redistributables packaged per-user. GOG uses system-wide libraries, resulting in a leaner 10.2GB install vs. Steam's 12.5GB.
Q: I can't find the multiplayer lobby.
A: Ensure both you and your friend are on v1.51. Crossplay between GOG and Steam is not supported in this patch (only GOG-to-GOG).
