Hi Gianfranco,
Glad to support such nice game as hedgewars.

Was not aware that hedgewars was build depending on FPC. Nice to know so that
next time we can test before uploading a major release.

Fine not open? Are you sure the Reset/ReWrite/... open function did not return
an error? Maybe check IoResult after opening the file.
Anyway this is strange as it would not worked before unless the OS backend open
function use is not the same as in previous version.
Can you please provide code snippet about when the file was open, which mode and
so on?

I'm almost sure this is not the faulty code, but something before that made the
file not correctly open.

I don't think we should remove any package form any arch, just be patient and
fix the bug.
