Marathon Update 1.0.9.1 Fixes Rook Spawns and Map Holes

Bungie rolled out a quick maintenance patch for Marathon, resolving a bug that trapped Rook inside shipping containers on Perimeter alongside various stability fixes.

Update 1.0.9.1 for Marathon arrives to smooth out navigation and map geometry issues across active sectors. The patch directly targets frustrating positioning bugs, including an issue where the Runner Rook could accidentally spawn trapped inside shipping containers on Perimeter.

Runner and Zone Fixes

The update resolves an issue on Perimeter where Rook spawned inside shipping containers. In the Hauler area, developers fixed a bug causing map geometry to disappear at specific distances. Over in Cryo Archive, a fix stops Crews from slipping into the airlock after the Compiler has already activated.

UI and Item Economy

Item previews no longer briefly display incorrect items when players inspect nearby loot. The update also clears up confusing item-related interface messaging across specific flows and fixes multiple issues where UI elements, notifications, and states displayed outdated data.

Stability

A broad assortment of background issues leading to client crashes, unexpected disconnects, and general network or software instability have been addressed.

Why this patch matters

This minor update cleanly targets geometry exploits and annoying spawning bugs without altering core balance or progression systems.
