Bus Simulator 27 Update 1.10 Targets Crashes and Junction Logic

Bus Simulator 27 receives its third pre-access hotfix. Version 1.10 addresses stability blockers, traffic behavior, vehicle models, and menu navigation.

Bus Simulator 27 is rolling out its third pre-access hotfix. Version 1.10 addresses multiple critical crashes, progression bugs, and AI traffic inconsistencies.

Stability and Critical Fixes

This update fixes several major crash causes. Changing the world time while sitting inside an AI-controlled bus no longer breaks controls or crashes the game. Acquiring large batches of buses, starting line service, and logging out of line service at the depot also no longer trigger infinite loading screens or lock up player inputs.

Traffic and Vehicle Tweaks

Junction priority roads, roundabouts, and left turns have received right-of-way behavior adjustments. AI buses now display rear lights in the evening. Turn signal penalties remain disabled by default. On the vehicle side, the Mercedes-Benz Citaro front-row seating issue is fixed, flipped right-side mirrors are corrected, amber light setups are improved, and front window wraps are adjusted.

UI, Audio, and Visuals

The Line Details screen is streamlined with the Drive button now pre-selected. Arrow-key and A/D navigation after mouse or settings inputs now work without locking menus. NPC heads and bodies no longer vanish at camera edges, and a shader compilation indicator now appears on startup while engine audio bugs during boot are resolved.

Why this patch matters

Version 1.10 is a reliability patch that cleans up progression stoppers and tidies up minor traffic logic.
