Any change MAY trigger your project to be placed on the manual review list.
The algorithm that determines this is secret, but one day you can make changes, even upload a new version, and your game will still be indexed. Another day you might fix a typo in the text, and it will be sent for manual revision.
The time it takes to be reviewed and reindexed varies greatly, from a few hours to weeks (also remember that the staff doesn't work weekends). If a significant amount of time passes, you can explain your situation and ask the moderator if they can expedite the process.
By the way, this forum is answered by the community; the staff does not read or respond here.
