PEAK Beta Patch 1.61.b Restores Cold Nights and Fixes Custom Run Progression

PEAK beta patch 1.61.b brings back cold nights on Ascent 5+ and custom runs. The update also addresses multiplayer disconnects, campfire synchronization, and rope hitching issues.

Beta branch patch 1.61.b for PEAK adjusts environmental hazards, multiplayer mechanics, and custom run rules.

Environmental and Custom Run Adjustments

Nights are cold once again on Ascent 5 and higher, as well as on custom runs when the setting is enabled. Guidebook pages will no longer spawn during custom runs, and progress toward multi-run achievements is disabled in custom runs.

Multiplayer and Connection Fixes

Players who disconnect in Caldera and reconnect in the Kiln will return dead unless a revive statue was used for other scouts. Reconnecting players will no longer fail to spawn their scout, and campfire lit states now properly sync for players who join after a fire is lit but before it burns out.

Performance

A major rope bug causing game hitches when multiple ropes were placed in the same biome has been resolved.

Why this patch matters

This beta update shores up multiplayer synchronization issues and tightens custom run restrictions while fixing a heavy rope-placement performance drop.
