Only Intel would be able to tell you. 

Have you tried deleting the db/ and incremental_db/ folders? if that doesnt work you will need to raise a support ticket.

Hi, tnx for the reply, yes I did delete those folders, also created new project but it is the same. 

Edit: Fixed. Project I was trying to compile was designed for Cyclone III and not for Cyclone V I was trying to use. By changing settings in existing megafunctions from C3 to C5 everything compiled perfectly either on Q13.0 or last one Q17.02.
