Diablo Immortal has another gem-related complaint on the table, and this one lands in exactly the sort of menu where players really do not want ambiguity. A fresh bug report says either the gem description or the progressive upgrade preview is showing the wrong numbers for a legendary gem upgrade. Which means one of two things is happening: either the text is lying, or the upgrade screen is. Neither option is exactly comforting when gems sit so close to power, progression, and wallet pain.
The report appears in Blizzard’s latest Diablo Immortal bug listings under the title “Either gem description or progressive upgrade preview has wrong numbers”, active on April 16, 2026. The public listing is small, but the premise is nasty enough on its own. If the description for a gem says one thing and the progressive upgrade interface says another, players are left guessing which number is actually real before they commit resources. In a game built around incremental upgrading, that is not a small trust issue.
When the UI argues with itself, players stop trusting both sides
This is the kind of bug that can look boring from a distance and feel awful the second it touches your account. Plenty of systems in Diablo Immortal are already fiddly enough without the menus starting an internal argument over what your upgrade is actually going to do. If one screen shows a stat increase and another suggests a different result, the player is stuck in the middle trying to decide whether the problem is bad wording, bad preview math, or a genuinely broken upgrade path.
And yes, players will absolutely care about that more than Blizzard would probably like. Gem upgrades are not just cosmetic noise. They are one of the game’s core progression systems, and they are tangled up with time, grind, and in plenty of cases real spending. The second the UI looks unreliable there, the whole thing starts smelling expensive in the worst possible way.
Diablo Immortal keeps coming back to the same cursed room
This is also not happening in a vacuum. We recently covered how players reported a legendary gem disappearing after a Rift, how a Leviathan Surge upgrade allegedly consumed 9,000 sigils and gave nothing back, and how Survivor’s Bane rewards were reportedly showing up more than once. Different bug shapes, same broad result: systems tied to rewards and progression keep looking shakier than they should.
That matters because once players start seeing a pattern, even a smaller UI-side report gets more attention than it normally would. In another game, mismatched preview numbers might be a footnote. In Diablo Immortal, it lands in a community already primed to side-eye anything involving gems, rewards, or upgrade menus.
Fresh report, small thread, bad category
To be fair, this is not proof of some giant gem-system collapse. The public report is still small, and Blizzard’s forum listing does not by itself show a huge wave of confirmations. Nobody should pretend otherwise. But this is still a very live and very sensitive category of bug. If players cannot trust the number shown on a gem description or the upgrade preview, they are not just dealing with bad UI. They are dealing with uncertainty right at the point where the game asks them to spend scarce resources.
At this point, Diablo Immortal does not just need its gem systems to work. It needs the numbers on screen to stop looking like they are negotiating with each other.
