Not every Diablo 4 problem this season is about missing rewards, broken damage, or failed trades. Some of the complaints hitting players are smaller on paper but still ugly in practice — especially when they affect cosmetic systems people paid into. A new PC bug report posted on March 31 says the player cannot change the appearance of their shield, weapon, or headstone, and also cannot swap pets, with the issue described as ongoing since the start of Season 12.
That makes this one more than a throwaway wardrobe annoyance. Cosmetic friction tends to get dismissed until it touches things players actually use every session, and in Diablo 4 that includes pets, mounts, portals, weapon skins, and individual armor looks. If those systems stop responding correctly, part of the game’s customization layer starts feeling jammed shut.
What is happening
The fresh March 31 report is short and direct, but it lines up with a wider pattern from earlier in the month. On March 11, another PC bug thread said players could not select individual armor skins, could not equip pets, and could not select weapon skins or effects properly. That same thread also described a specific wardrobe problem where clicking once could apply the full set/theme instead of just the chosen piece.
A separate general-discussion thread from March 11 described similar symptoms: no pet selection, no mount changes, and individual clothing pieces behaving incorrectly. By March 12, players in that thread were already sharing temporary workarounds, including holding left click and tapping space bar to get some appearance changes to register. Another bug thread described a similar mouse-button workaround for pets, mounts, portals, weapons, and shields, while noting that armor-piece transmog still remained broken.
Why it matters
This matters because the problem seems to cut across both convenience and monetized customization. One March 12 post explicitly tied the bug to frustration over a Reliquary purchase, with the player asking about refunds after saying they could not use pets, transmogs, or mount changes. Even if that is just one player’s reaction, it shows why cosmetic bugs hit differently when they overlap with paid systems.
Current status / what Blizzard said
So far, Blizzard’s public Season 12 known bugs roundup does not list this transmog/pet issue in its main bullet list. Players did raise the problem inside that known-bugs thread on March 14, mentioning broken transmog selection, pet choice, and mount issues, but it does not appear as one of the officially summarized items in the top post.
When “just cosmetics” stops being minor
A broken reward stings. A broken build hurts. But when Diablo 4 starts fighting players over how their character even looks, the season starts feeling messy in a different way — and a lot more personal.
