Direct answer

Since 1.0, non-production devices no longer unlock from the Tech Tree — they unlock at the Workbench instead. Quote from the official 1.0 patch notes: “Removed all non-production devices from the Tech Tree. These devices must now be unlocked at the Workbench.” If a building or decoration you used to research is missing, open the Workbench unlock UI — that is where it moved.

Why it changed

1.0 re-architected unlocking. The Tech Tree now focuses on production devices; everything else (buildings, decorations, service items) was moved to the Workbench. The same patch also merged shop-sales- and purchase-contract upgrades into the Shop Recognition system, so parts of the old tree genuinely disappeared rather than moving.

Old-save notes

  • Hotfix 1.0.4917 fixed an issue where old save files could refund skill points multiple times after the update.
  • If something feels missing from your pre-1.0 save, check hotfix notes first — several “missing” systems were addressed in 1.0.4917/4930/4940.
  • Workbench-related UI had a bug fixed in 1.0.4917: “the building panel would remain visible when building an item.”
If you still cannot find it

Confirm the device is a production device (Tech Tree) or not (Workbench). Community reports of “vanished” items after 1.0 usually trace to this split, not data loss.

Unlocking changed broadly at launch — see Research for the tree, Catapult unlock for that specific device, and 1.0 systems for the Shop Recognition merge.
