Data was lost upon exiting and re-entering

[nus-pe-bot]

Whole app data was lost when I exited and re-entered the app upon doing the following steps:

1. From first launch, execute command inspect 1 to inspect Alex Yeoh
2. From inspect window, execute add i/Chair e/2025-04-04 a/John street, block 123, #01-01, S123456 c/$200000000000000000000000 s/delivered. (command is executed successfully without any error thrown)
3. Exit and re-enter app. Data is lost as shown in screenshot above.

Expected: error to be thrown initially when app cannot handle such big number.

Team's Response

• This is a similar issue to #3753.
• This appears to be a case of extreme user input, as we believe that the input cost, 200 sextillion, is 2.5 billion times the total amount of money in the world. Thus, no reasonable delivery cost should contain that amount of money.
• Also, it is highly unlikely that user mistakes will cause such input as 23 deliberate '0's are required to be entered for this to happen.
• As stated by the course website, problems caused by overflow due to extreme user behavior is not considered a bug, so the team has decided to reject it.
