Build 26525157

COMPARTMENTS AND FIRES

• Sealed compartments now behave. A compartment that burned out while sealed
can be unsealed again, crew will not walk through a sealed door or into a
destroyed space, and a burnt-out sealed compartment no longer drains the
health of anyone inside. Wrecks show DESTROYED instead of SEALED.

• Fires are about three times rarer and properly spaced. At 1× time you should
see roughly one fire every four hours of game time, instead of one every
~1.4 hours; a typical one-hour patrol now has about a 1-in-4 chance of a
fire, and serious fires are very rare. Time compression no longer turns into
a fire hose at 16× or 64×. Electrical faults and fuse trips remain common.

• Fires are still random, not scripted. Two patrols in a row can both have one;
that is unlucky, not the mission forcing it.

STARTUP AND SUPPORT

• MENU → SUPPORT → COPY DIAGNOSTICS copies a report to the clipboard and writes
diagnostics.txt next to your saves: version, display and GPU state, the tail
of launch.log and error.log, and the active launch flags. Paste it into a bug
report instead of hunting for files.

• MENU → SUPPORT → RESTART IN SAFE MODE saves and relaunches with software
rendering and compatibility flags — useful if a driver or display change
leaves the window wedged.

• A startup watchdog now relaunches once in safe mode if the first page load
never finishes (25 seconds). It logs the timeout instead of looping.

READABILITY AND FEEDBACK

• The loss screen now tells you why the boat was lost and gives a short,
cause-specific tip: fire, flooding, crush, torpedo, reactor, crew loss or
grounding.

• The header alarm bar is sorted by urgency — loss and crush first, then
fire/flood/weapons, then electrical and air faults, then situational
warnings. Red/amber styling follows the same order.

• Idle canvases now redraw on new snapshots and input instead of every frame.
Static views drop to the ~10 Hz snapshot rate; the periscope and radar keep
30 fps. Less fan noise and heat on laptops.

No new content in this patch. The next update is the UI scaling and theme work.

Thanks for the reports, the logs and the Steam threads — they made these
findable.
