Let's see, I'm going to explain it one last time.
What happened to you is normal, the fact that it hasn't happened to you before doesn't mean anything.
There is an automatic algorithm that can place (please note the can, not that it always does) an update or new game on a list to be manually reviewed, when that happens, that game is removed from the itch index until it is reviewed by a staff member.
The same thing has happened to dozens of other people and there are dozens of posts on this forum talking about the same thing. If you don't believe me, you can search. That's why we tell you that what happened to you is normal.
So you understand, it's like when they make you open your luggage at an airport, you can go around 100 times and they will never ask you to check anything, and one day, they may ask you. It's the same.
Since the algorithm is secret, the staff will never tell you why it was activated in your case, period.
Every time you update or upload a new game, there is a chance that it will happen again, to you, or me, or anyone, it's that simple.
The other games have very recent updates and all of that together, it looks suspicious, I don't say that you are doing anything wrong, I mean that those kinds of patterns are the kind of patterns that raise suspicions and maybe that will lead to your other games not being indexed. This is just a guess.
What I can tell you is that uploading the same game again to try to bypass the manual review is usually considered cheating and from what I have read in other cases, it can lead to a penalty on your account, my recommendation is that you do not do it.
If you have already contacted support, it is best to wait for an official response from them.
I remind you that here we are other users who answer and I can only try to guide you based on what has been written in other posts that talk about the same thing.
