Zora spends the time 17 days tracking the cause, she needs the ship to do jump to test something then comes back with finding.
The time bubble that goes around ship is not uniform. So there are parts of the outer hull not in time stop field. These parts age at normal rate and since it takes millions of years to get to places we go without time stop bubble its wears on hull. It means that every time we jump hull takes some dmg that has to replace.
If we find someone that can uniform a PL 11 time bubble that we trust maybe can srop it 😉
