Schematic research: why did my mod disappear?

Follow these steps

1. Separate the pickup, the research and the item

   First identify which state changed. The November 8 community replies describe researched mods joining the normal item pool and appearing in later runs. Their explanation does not promise the same mod at every run start.

   Three different things players call a schematic

   State	What to check
   Found schematic	You took a blueprint during a run. Our checklist records only that find; it cannot read your game save or complete research.
   Researched unlock	Check the schematic's research status in the hub. Current players describe completed research as adding the mod to possible future loot.
   Physical mod	This is the usable item you carry in a run. Earlier player accounts explicitly describe losing that item on death without losing the researched loot-pool unlock.

2. Check the hub's research status, not just your loadout

   If the mod is missing from your inventory, return to the hub and check the named schematic's research status. If research is unfinished, follow the requirements displayed in your own game. If it is complete, an empty loadout alone does not show that the unlock has been deleted. One current player specifically describes collecting a fully researched hub item for the next run.

3. Treat future drops as possibilities

   A researched item joining the normal pool means it can appear again; it does not establish a guaranteed drop, a fixed number of runs, or a permanent starting item. Do not repeatedly collect the blueprint solely because the mod failed to appear in one run.

4. Distinguish an old bug from your current save

   The September 3, 2025 patch fixed an early-access bug that lost a researched schematic item when swapping starting weapons. It also said players affected by a specific Quickdraw issue might need to find and research that schematic again for it to enter the loot pool correctly. Those are dated fixes, not instructions to re-research every schematic after a death.

5. Do not assume an unverified extraction requirement

   An early-access player describes dying and then researching the schematic at base. That is historical evidence, not a complete 1.0 rule. The 1.0 notes also fixed schematic pickups during the escape sequence; that fix does not say ordinary pickups require a successful extraction. A current universal extraction rule, research costs and exact completion sequence remain unconfirmed here.

Completion signal

You have checked the schematic's research status separately from the physical mod in your inventory. If research remains complete and only the run item is gone, that matches the community's unlock-versus-item explanation.

If it does not work

If a completed research entry actually reverts or the game contradicts this explanation, record the schematic name, your build version and the research status before and after the problem. Use the game's current glossary/intel and report the specific change. The historical Quickdraw fix does not establish a universal remedy for a 1.0 save.

The main explanation is from players replying on November 8, 2026, not an official specification of every 1.0 research state. The Steam discussion and September 2025 fixes are early-access history. No current research price, timer, extraction exception or guaranteed drop rate is claimed.
