Transport Fever 3 Crash While Loading a Save — Official Checks

Quick facts

Platform

PC mod-enabled installation

40420 status

Named rendering/UI/dependency fixes do not prove all save-loading crashes are fixed.

Independent reproduction

Not performed

Official troubleshooting sequence

1. Try loading with all mods disabled. 2. Sign out of the mod hub and restart. 3. Official support next recommends clearing the shader cache.

Identify the symptom first

Distinguish one affected save from every new game. Compare a copied save and a clean test while recording the active mods; missing dependencies and shader errors are hypotheses until a log or reproduction supports them. Never overwrite the only modded save while testing.

Patch and platform status

Named rendering/UI/dependency fixes do not prove all save-loading crashes are fixed. Steam Stable 40420 is documented on October 8, 2026. The PC notes do not confirm that Epic/GOG or consoles received the same patch. Their latest numbered official entries and the announced rollout are displayed separately. Check the installed build in the main menu; a manual or support source check is not an independent live-build test.

Data safety and unresolved causes

Back up the affected save before diagnostic changes. Use a copy and do not overwrite the only modded save during testing. Locate the shader_cache folder via the official file-location guide; do not delete the entire userdata directory. Cause-specific confirmation and device-specific success remain Unknown. Before reporting, record the store/platform, installed build, operating system, hardware, mod versions, affected save and exact reproduction steps. Keep the relevant stdout.txt and crash files before another launch overwrites them. Use a copy of a save for diagnosis and the official support form for unresolved failures; no successful reproduction or guaranteed remedy is claimed here.
