Lemme add some more to this, since I've got some other visual bugs that have been approaching years in lifespans...
Nychus MOA has its turret caved in and sunken into the neck. This bug appeared only a few months after the Nychus' release, and has been unfixed ever since.
All Operator Amps had their scaffoldings, which should be on top of the bracer, permanently misaligned the wrong way to the point where they all clip with the Operator's own hand, also unfixed ever since.
Xaku's Xata's Whispers at first showed a Void-like overlay over the Warframe, but within a manner of weeks, Xata's Whisper's visual effect took on an infested appearance, and has been that way ever since.
Literally ALL DE-made Nikana models have their handles clipping into the hand of the Warframe. Tennogen weapons actually have corrected this on their end, an embarrassing case of third parties doing better than DE themselves...
On top of the Syam being misaligned out of its sheath, the longer sword of the Sun & Moon Dual Nikanas is clipping out of the tip of its sheath.
These visual bugs have been present for so long, they're slowly becoming "features", much to my dismay. I don't know what's going on at DE over there, but perhaps things are being backlogged in favor of other things? Nevertheless, all that ugly is starting to pile on and is starting to add up. There's probably many more visual bugs than the one present here, and I know DE may be having to juggle a bit with all sorts of other things, but the fact that all of these visual bugs can be tracked, listed off, and all confirmed as unfixed, as well as how long these bugs have persisted may give a pretty dour image of DE's quality control...
