This map had a problem texture on the Loxophilia server. The textures/whir/of_wall.wal file was corrupted on the http side of things for some reason and this caused clients to disconnect in ERROR mode once the file failed.

The wal file has been fixed. The correct wal file has 10,980 bytes.
To correct the error on your client, delete the bad (18k byte) textures/whir/of_wall.wal from your computer and when urbanic is next selected on the servers the correct wal file will be downloaded.

Loxophobia appears to have had the correct file.
