I just tried to move my Plugin from 11.5 to 13.
Sadly, now the AddJoint function does not work anymore

  
n = weightTag->AddJoint(*l);  

after this, n equals -1.
*l is a valid Joint, as a call to

(*l)->SetName("Test");

works without any problems

Sadly the documentation does not include any information why this function could return -1.

Is this a bug within the API?
Or what else could be the reason?

AddJoint() can return -1 if the tag is not present in an object's tag list.
Take a look at this post and the given code sample: https://developers.maxon.net/forum/topic/5251/5246_addjoint-setweight-crash&KW=AddJoint&PID=21514#21514
