Targets module lost in Studio

[vguna]

Hi.

OS: Debian etch
Sugar: 5.5.0 CE
Webserver: Apache 2
PHP 5
Mysql: 5

We're using the Targets function to store potential customers. So we added some custom fields to the Targets object via Studio. After a while I encountered, that the "Targets" Module is no longer existing in the Studio. How can this happen? In the sugarcrm.log is no sign of an error. Any hints?

Also another question, a bit off-topic:

When looking at TargetLists I created with Targets in it, how can I do a mass update on Targets contained in this specific TargetList? There's no sign of any field for mass-update there. Looking at _all_ Targets allows mass-updates though.

Regards,
Veit

After upgrading to 5.5.1, Targets module appeared again.
