Crash and inconsistent mapping

There are 2 different behaviors that occur in this context.

1.) In the attached project the yellow marked slave was deleted and inserted again. Then the signals of this slave are mapped and a download is performed. 
-> Now the gateway reports an inconsistent configuration.
If the mapping of this slave is deleted now, the gateway accepts the configuration. 

2.) If the signal mapping of the gateway is now changed to "Auto mapping" and a download is performed, SYCON.net crashes with the message "Buffer overrun detected".

If the configuration is created again, these problems do not occur.

In the attachment you can find the corresponding EDS file and also a project where the problem occurs.
