Unable to upgrade artifacts.

Since last night, I am unable to upgrade 3* artifacts which are created in last 24hrs. Already reported to CS but no solution. For 1% buff, rather than upgrading to 2%, it's starting from 0 and ending to 1% again while wasting resources and blue print.

I have the same issue while leveling up a benefit of artifacts (they leveling up to the same value as it currently has). All common main hall and war hall artifacts are affected by this bug (no matter if new or old ones). Legendary artifacts level up normaly. I have contacted CS several days ago. They responded in a way that they forward the issue to the development team. There is no fix yet.

For me it stared just after I finished new lib research to reduce 5% blueprints cost. Is it same for you?

I'm not absolutely sure, but I also suspect the library research has something to do regarding the bug. I went for the blueprints reduction research prior to leveling up my artifacts.

I also saw the effect just after I leveled the first blueprint reduction research tier (lvl 4)
