I have several tasks within a WBS.
These tasks have no linked tasks (no predecessors and no successors).
The WBS however is linked to other WBS's (1 predecessor and 1 successor).


I want to link the tasks within the WBS but get the message:
"These tasks can't be linked because they're already linked through another task chain"


Again these task do not have any successors nor predecessors, their WBS does.


I expect to be able to link these tasks within the WBS.
