The developers have fixed several technical issues.
Blizzard has returned to Diablo II: Resurrected and introduced a small hotfix aimed at solving several technical problems.
Fixed a bug that prevented Colossal Jewels from dropping after fighting uber versions of the ancients if the player entered and exited the portal during the battle in offline games.
Also fixed a bug that caused the Chronicle to reset when identifying unique items dropped from armor or weapon racks. This applies to online and offline games.
In addition, "various stability improvements" have been implemented in Diablo II: Resurrected.
