Graveyard Keeper 2 Known Issues & Bugs

Quick answer: These are the issues tracked through the demo. Almost all are unresolved with no developer reply as of the demo end. Post-launch status is being re-verified — none has a confirmed official patch as of 2026-09-26. Where a third-party mod exists it is noted, but a mod is not an official fix.

Important: the pinned developer "Known issues" thread is a reporting guide only — it gives a driver / minimum-spec / verify-files checklist and report instructions, and names no specific bug. Do not read it as a bug-acknowledgement list.

Crematorium fails to burn bodies

Doors don't close, the countdown never starts, the corpse can't be removed, and later the building can't be interacted with at all.

Status: Unresolved in the demo. 8 comments, multiple independent reports, no developer reply.
One poster restarted from scratch and rushed the crematorium with no bug — the problem appears to arise and persist only in certain save files.
Post-launch: unverified. Discussion

Green Thumb perk does nothing

The advertised +2 planting/harvesting mastery isn't added to the shown value or checked when planting.

Status: Unresolved, no developer reply. Reported in both the general and bug boards.
Players disproved the "raises plot base quality" theory (that comes from the garden expansion, base 2 → 4). Broader suspicion that several demo perks are non-functional (Forager, Preacher, Axeman named).

Cube Distillations perk — preview vs output

The distillation perk bonus shows in the crafting preview but isn't applied to the actual output. Fat previews 7 but yields 4; seed oil previews 5 but yields 3.

Status: Unresolved, no developer reply.

Fishing bait can't be made

Status: Unresolved with no real answer — the thread has two joke replies and the poster never returned. No source confirms or denies a bait recipe.

Zombie supplier station wipes tech points

Assigning a zombie to the Zombie Supplier Station wipes all its unspent tech points to zero, permanently (21 green / 151 red reproduced on demo v1.002.4); unlocked perks survive.

Status: Unresolved, no developer reply. A third-party Nexus mod targets this exact bug — not an official fix.

Tutorial first-corpse soft locks (two reports)

Report 1: body placed outside the accepted area loops the "put a sign" prompt and pushes the character back. Zero replies.
Report 2: first corpse dumped in the river, main quest stuck and the hammer unobtainable. Zero replies.
Status: Unresolved, no developer response on either.

Steam Deck — performance & Verified

Status: Mixed. The official pinned FAQ says the game will be "at least playable" on Steam Deck at launch, with Verified as the goal. Players report low/lowest settings remove stutter; one finished the whole demo on Deck at high settings.
A third-party review lists Steam Deck compatibility as Unknown/unrated by Valve at time of writing, and warns the menus are fiddly.
Post-launch: check the store page for a Valve rating. FAQ · Review

Ultrawide / super-ultrawide

Status: Unresolved and unconfirmed — no developer statement exists. Players report no ultrawide support in the demo (3840×1080 gets black bars; can't set the monitor resolution); the first game also needed a third-party fix. 32:9 remains open.

First grave troubleshooting · Zombie not working · Study Table & research · Fishing · Technology · Demo

Sources: Steam community bug-report and discussion threads, the pinned developer FAQ and one third-party review. All statuses reflect the demo; post-launch re-verification (12 items) is tracked separately and none is confirmed fixed as of 2026-09-26. Where a mod is mentioned it is a third-party workaround, not an official patch.
