Hello everyone!
We're finally done with the verification process of 2.7.2, and in addition to the fixes on the beta branch right now we've added a few more. Thank you for your patience :)
If you wanna read the full patch notes, see the forum post
hereSave games shouldn't be adversely affected by the switch from 2.7.1 to 2.7.2, but just in case you do encounter issues, you can roll back to a prior version via right click on Stellaris in library -> properties -> betas -> choose the desired version.
If you want to do crossplay MP between Steam and our other release platforms (Plaza/GOG/MS Store), you need to opt in to the crossplay beta "stellaris_test" by the same method.
