ArgumentException #8

Hi there,

just tried using the Savegame Visualizer, which threw an error relating to FileDBReader. So I tried running FileDBReader on its own, using:

FileDBReader decompress -f "..\test\Christian Jäger_S87.a7s"

which gave me the following error:

[READER]: Autodetected FileVersion = Version1
Unhandled exception. System.ArgumentException: An item with the same key has already been added. Key: 0
   at System.Collections.Generic.Dictionary`2.TryInsert(TKey key, TValue value, InsertionBehavior behavior)

   at FileDBReader.CommandLineHandler.Main(String[] args)

For what it's worth, the program auto-detects FileVersion 1, which seems odd, as I am using the latest version of Anno 1800.

Using the command

FileDBReader decompress -c 2 -f "..\test\Christian Jäger_S87.a7s"

does not do anything (at least not to my eyes), the error is still the same, I think.

I just tried several other save games, every one gives me the same error.

Am I doing something wrong? What's going on?

The savegame is no filedb file.

It's an RDA archive containing 4 files. each of these is zlib compressed (and at least from my knowledge, has custom file headers).

The uncompressed results are filedb files.

I Should improve exception handling here tho.
