From time to time: java.io.FileNotFoundException: logs/current/20150326T110200/wall_shifts.json

After a few successful attempts at wall shifts, I get an exception :

ERROR - java.io.FileNotFoundException: logs/current/20150326T110200/wall_shifts.json (No such file or directory)

[Benjamin Cordes]

AFAIK starting several bots should be impossible (?), otherwise I would have guessed a different process is moving folders. At the beginning the folder is created and set. Afterwards it appears to been moved by another process or move is called wrongly (currently don't understand how this could happen). Will fix this issue ASAP.

Added some logging about session folders.

[Desrever Nu]

Is it possible that some other NuBot instance is moving folders?

Not that I am aware of. Double checking now.

[Desrever Nu]

But AFAIK starting several bots should be impossible (?).

It is possible, actually, and this might be exactly what happened.

[Desrever Nu]

has been caused by multiple instances of the bot running simultaneously
