SOPC: connection type interrupt not available

Hi,

When I open a multicore project developed in 8.1 with Q10.0sp1 then I do get a bunch of errors for every connection of type clock or interrupt:

connection type interrupt not available

connection type clock not available

By toggling each connection the error goes away, but if I save the file and then opens it again the errors are back.

Anyone seen this?
