Allumeria Crashes, Fullscreen and Save Problems: Fixes

First: are you on the current patch?

Allumeria shipped four patches in its first four days, and most launch-week problems have a fix in one of them. Steam updates automatically unless you have told it not to. The version you want is 0.15.4 or later.

Crashing when breaking blocks

This is the big one, and the developer has been open about it: they could not reproduce it locally. Two mitigations shipped anyway —

• 0.15.1 — an attempted fix for the crash that happens occasionally when breaking blocks on some machines.
• 0.15.3 — a try/catch added around the function that appeared to be causing crashes.
• 0.15.4 — that try/catch around Mesh.Draw was replaced with a null check, which is the more correct fix.

If it still happens to you, the useful thing to do is post in the Steam discussions with your specs — this is a bug that survived because it does not reproduce on the developer’s machine, so reports are what will fix it.

Before assuming it is the game, check the two hardware requirements that the store page hides in the notes: at least 2 GB of VRAM and OpenGL 3.3. Those knock out a surprising number of old integrated GPUs that otherwise meet the modest spec.

Fullscreen problems

• F11 toggles fullscreen. It is a debug key, not a setting, which is why people cannot find it.
• 0.15.1 fixed the fullscreen state resetting when you exited the settings menu, and made exiting fullscreen from settings restore the window to the centre of the screen.

Corrupted or missing saves

0.15.1 fixed a bug where autosaves could occur on the loading screen, which caused save corruption. It also fixed the autosave on/off setting not applying. If you had a save go bad during launch week, that was probably it — and it is fixed rather than ongoing.

Interface and input oddities

• UI unresponsive at 1× scale — fixed in 0.15.0.
• Escape while rebinding keys now exits keybind mode rather than binding Escape (0.15.1).
• Shift-click deleting items — auto-stack and auto-delete were split onto separate hotkeys in 0.15.0 (shift-click and ctrl-click by default) because they used to share the place and drop modifiers.
• Held item stuck on screen when closing the inventory — fixed in 0.15.1.
• Third person is F5, with a setting for camera placement (front, back, freecam).

Things that look like bugs and are not

• An NPC will not move in. That is the Comfort check, not a crash — enclosed room, light level, and the NPC’s specific requirement. 0.15.2 fixed the worst room-detection issues; see the NPC and housing guide.
• Ceiling collapses in the desert dungeon after you extinguish an altar. Intended.
• KeyPad7 crashes the game. Also intended — it is a documented debug key.
• Forest Keys not dropping. Since 0.15.3 they do not drop until the Forest Spirit is dead. Working as designed, and a change from older guides.
• Freezing killing you fast. 0.15.1 raised freezing damage from 8 to 30 every two seconds. You need the Frozen Heart trinket, not better armour.

Where the files are

Settings has buttons to open the various game folders, and the skin selection menu has its own “show folder” button. That is the supported way to reach asset packs and skins rather than typing paths — see mods and asset packs.
