- QTESystem: add if (!this.active) return guard in setInterval/setTimeout
callbacks to prevent false result from firing after successful key press
- SaveLoadMenu: restore auto-save slot 0 row with blue styling, thumbnail,
scene label, and read-only load button
Previously maxLimit was passed directly to setTimeout/setInterval (ms),
so a JSON value of 10 meant 10ms instead of the intended 10 seconds.
Now timeLimit in JSON represents seconds, engine multiplies by 1000.
The first onUpdate call used raw milliseconds (e.g. total: 10000),
while subsequent ticks used seconds (total: 10). This caused the
progress bar to jump on the first interval tick.
