Fata Deum Version Update Patch Notes v0.1.8 — Memory Optimization & Crash Fixes

November 6, 2025
ModeZone

We’re pleased to announce that Patch 0.1.8 has now landed on the Beta branch!

As we noted in our last Steam news, this update brings two new elemental Orbs – Earth and Wind!

The Wind Orb lets you throw or place wind‑thunder devices. When triggered by mortals, they scatter everywhere! Use them to shield your settlement from attackers or sabotage trade routes.

The Earth Orb is a massive magical stone; toss it to severely damage buildings, or drop it as a “gift” so your mortals gain a large amount of stone, an essential resource for construction.

Along with these new features, this patch includes various other changes, fixes, and improvements.
Below is the full changelog for your reference:

✅ Additions
Two new elemental Orbs (Wind and Earth).

Wind Orb: throw or place wind‑thunder; when triggered by mortals, they scatter. Protect your settlement or disrupt trade.

Earth Orb: a large magical stone; throw it to heavily damage buildings, or drop it to provide large amounts of stone resource.

The tutorial has been adjusted to reflect the two new Orbs.

🛠 Crash / Performance Fixes & Memory Optimizations
Seeing lots of crashes during level loading or play? Many were caused by insufficient memory (RAM or GPU memory). We’ve worked hard to reduce this.

Lowered the memory consumption of the vegetation system.

Lowered the memory consumption of the large‑crowd rendering system.

Lowered the memory consumption of the terrain rendering system.

Lowered the memory consumption of the impostor rendering system.

Fixed a severe bug where invalid long‑term data was being stored, which over time degraded performance, bloated save files, and increased load times.

Fixed issue with delayed events on individuals still being kept in memory even though they had long since disappeared.

Added a safety mechanism: even if similar invalid data occurs in the future, it will be detected and automatically removed.
→ Players who experienced incredibly long save / load times in mid–late game should see improvements. (But we cannot guarantee it solves all cases; please get in touch with us with corrupt save files if you still experience issues.)

Added an extra mechanism: before initialization, we now scan saves to identify and remove this kind of invalid data.

Fixed another crash possibility: a waterless region based on terrain deformation could cause invalid memory access and crash some graphics cards.

🔧 Minor Fixes & Tweaks
Adjusted the tutorial for Orbs to reflect the two new elements.

Fixed issue: when migrating, some immigrants had no source settlement (mainly mission characters) — now resolved.
