Just updating to let you guys know that all the stuff listed in this post has been pushed to the stable branch! Translation: Everyone should have the latest update now. :)
Broken mods after the patch? Mod authors will have to update to the new .pak file format to keep their mods compatible.
Issues crafting skyrails? With the latest update, Skyrails have their very own special Skyrail Crafting Table which you can craft with the Metalworks Station if you’re at tier 4 or above. However, players who are already at tier 4 or above will need to re-use their tier 4 Starmap upgrade in order for the Skyrail Crafting Table recipe to appear in the Metalworks Station.
