MC-72068Corrupted Server Player Data Files
When I attempt to run my server on my computer, nobody can join because the client claims it is out of date, even though we are using the latest release (1.8) on both client and server. When I check the logs the server reports the following:
-
-
-
- DETECTED OLD PLAYER DIRECTORY IN THE WORLD SAVE
- THIS USUALLY HAPPENS WHEN THE AUTOMATIC CONVERSION FAILED IN SOME WAY
-
- please restart the server and if the problem persists, remove the directory 'World/players'
-
I am attempting to load up a world from 1.7.10. And yes, everything works perfectly when running in that version. But every time I try to use in 1.8, the server fails in the same way. I have tried at least four times.
Environment
Windows XP on Dell Precision 390, Java version 7 update 67 (build 1.7.0_67-b01); 32 bit system

This report has an incorrect resolution!
The reporter attached the complete log!
playerdata.zip
Please attach the complete server.log.
I have attached the server log.
Dupe of MC-33041
that's not true, this one has lines that one doesn't, and these lines is what this report is about:
MC-33041 deals with blank console output when using server.exe which is not a game-breaking issue. This is the server itself failing to run due to a bug in 1.8 when handling old player.dat files from the previous version.
Al, you sure? This showed up in the log as well.
This is right "Sonic", but I mean probably nearly 10% of all players have this (me included) because of anti-virus programms, but I didn't had this other bug yet...
Sonic this line appears in all logs even before 1.8, simply because the server gui does not output data. I'm pretty sure this has nothing to do with the bug being discussed.
What happens if you follow the advice
?
Well that's the issue: I don't want to have to make everyone start over. Although I have considered getting everyone to put all their items in chests, that would be hard to coordinate with all existing players in the database (those who play on the server). Also, aren't Ender Chests tied to these data files? As in those would be wiped also?
You can try that with a backup of the world.
Can you maybe also add those player files before you delete anything? you can zip them with for example winrar or just upload every single file, if they are not to many
Maybe we can find the bug then
Attached all player data as of 9/22/14. These are confirmed to be working in 1.7.10. Don't worry I make frequent backups, including before attaching these.
Just tested the server and figured out it was the PLAYERS folder, not PLAYERDATA that needed removal, the latter being the currently used directory. The former is from an even older version, as it does not have the player.dat files named with UUIDs, instead with user names.
Well, that's not quite surprising, because the server was telling to do so:
Yes I didn't realize there were two player directories in the save… At least now we know that it wasn't a major bug.
