Sovereign Tower Crash & Won't Start Fixes.

First, name the failure

'Won't start' and 'crashes during a cycle' are different reports. Write down whether the game closes before the menu, when opening the map, after a specific day, or after a particular interaction. Include your operating system, hardware level, and whether the issue is repeatable.

• Launch failure: no menu or immediate close
• Progression crash: closes at the same cycle or interaction
• Visual or result-screen bug: the game continues but the state is wrong

Try the low-risk checks

The developer's Steam response asks players to confirm that the device meets the minimum requirements, update graphics drivers, and describe the exact crash point. Do those checks before removing saves or reinstalling.

• Confirm the device meets the store page requirements
• Update the graphics driver
• Note the cycle, map, quest, and interaction that precede the crash
• Keep a copy of any useful error text before changing the install

Last resort: the developer's reset procedure

For a suspected faulty install, the developer recommends disabling Steam Cloud, uninstalling the game, deleting the old local save data, and reinstalling. The listed save folder is AppData\Roaming\Godot\app_userdata\Sovereign Tower (VS). This can reset progress, so treat it as a last resort and preserve anything you may need first.

• Disable Steam Cloud for Sovereign Tower
• Uninstall the game
• Back up the local save folder before deleting it
• Remove the old local save only if you accept losing that progress
• Reinstall and test the same failure point

What to include in a useful bug report

A short report with the build, hardware, cycle, exact interaction, and whether a clean reinstall changed the result is more useful than 'it crashes'. It also lets other players distinguish a local save problem from a repeatable game bug.
