Hi Juzujka,
I think you should file a service request to Altera to report this issue. Check out the following link to sign up an account to file the service request. Note that you will require a valid company email to sign up the account. https://www.altera.com/mal-all/mal-signin.html?resource=%2Fcontent%2Faltera-www%2Fglobal%2Fen_us%2Findex%2Fmyaltera%2Fmal-home.html&$$login$$=%24%24login%24%24 - Altera_Forum--- Quote Start --- Hi Juzujka, I think you should file a service request to Altera to report this issue.
