Gaping Maw showing +0 stats despite item file having +15/+6

Really minor, but in 1.7.2 I just got this unique from an orc patrol:

As you can see, it shows Changes Stats: +0 Str / +0 Wil, and Changes Damage: 0% nature.

Minor visual bug: +0 stat changes should be hidden from the item details shown t o the user, no? To reduce visual pollution.

Real bug: I downloaded the source for 1.7.2 (FYI, I wasn't allowed to anonymously clone the git repo, I was forced to download a zip file from the website. Why not allow anonymous clones?) and the file boss-artifacts.lua says Gaping Maw has inc_damage Nature = 15, and inc_stats STR = 6 WIL = 6. So for whatever reason the item didn't spawn properly.

The *bug* you describe occurs when an NPC that qualifies for antimagic bonuses is spawned with Gaping maw, and a character that doesn't qualify for antimagic bonuses picks the artifact up.
