After the «mage2pro/core» package installation the «Register» and «Log In» links are disappeared

After install allpay
My Create an Account link and login login link is lost?..
Is this a bug?

Yes, it is a bug, I am investigating it now.



It is a Magento 2 core bug, which could appear is some random circumstances when some third-party modules are installed.
I added a patch to the 1.8.10 version of my mage2pro/core package to fix it for my extensions case.
Do the extensions upgrade, and it should fix the problem.
