TortoiseSVN and file loss

Already noticed by several people that there are problems: svn takes the latest version from the repository, and not all files are taken. It can be seen that there are not enough files in the working folder, but they are in the repository, repeated update does not help. Saves the removal of the entire "sick folder" and update external containing. In general, be careful - version 1.6.x (this was on several versions).
