グループ画面でのグループタブの全ロスト

[ja1krg]

一昨日、グループ画面にあった20個以上のグループタブが全て消え、「全所属艦」だけになりました。
その前後で、グループタブの追加や変更は行っていません。
不便なので、現在は新しくタブを追加して使っています。
アプリのバージョンはVer.5.3.6.0です。

Is there any error in logs?
The most likely reason is that "Settings\ShipGroups.xml" got corrupted somehow.

The contents of the error log are pasted below.

Error Report [ver. 5.3.6.0]: 2024/07/22 19:12:44

Yeah, the file got corrupted somehow, so there's nothing we can do here.

[ja1krg]

Understood. I'm assuming my data won't come back...
That being said, if there is no way to recover it, and if this kind of trouble is occurring more or less, I think the app needs to process the backup. This is just a request.

[ja1krg]

This issue has occurred again. It has never happened before, but it has happened twice recently. Is it really just my environment's fault?

[myangelkamikaze]

Can you upload the ShipGroups.xml file?
Note that it'll be overridden when you close 七四式, so you need to make a copy before that.

[ja1krg]

I haven't closed the app yet. I can't send it as it is, so I'll edit the extension to txt and send it. By the way, the contents of this file look blank.

ShipGroups.txt

[myangelkamikaze]

I get this. Is that the content?

[ja1krg]

No, it really is a zero byte file. For example in a hex editor it looks like this:

[myangelkamikaze]

Hmm, maybe something happens when the file attempts to get saved. Can you check if there are any errors in the windows event viewer?

[ja1krg]

I checked the logs. There are several logs from the time in question, but none were from EOBrowser.exe. Instead, the security software and Nkdnssd Servive (?) were reporting errors.

[myangelkamikaze]

That's from a different application.
Are you getting unexpected crashes or anything?
Can you check if your disk is okay?

I have no idea why that file would be getting corrupted if there weren't any unexpected crashes or something like that.
