The following shoulder accessory’s particles appear at the origin point because they’re in the incorrect location, they should instead be inside the Handle part or at their own attachment point. Currently they are inside the Accessory only.
I could say with relative confidence that over half of the gear I own is now broken in some way; it would be nice for users to be able to actually use the gear they paid for, but I doubt it’s in Roblox’s best interest business-wise to do a mass-fix of all of their broken gear when they could be working on improvements to the platform. Maybe trusted users like yourself filling that role voluntarily is a way to go.
The second one would be the Trial of Development hat. This issue is slightly different, yet similar enough to be brought up. There’s a Trail inside the ParticleEmitter of this hat, which is supposed to leave a blue trail as the character walks around. However, only Attachment0 is set, leaving the other field blank and the trail unusable. It also happens to lack a proper thumbnail.
This isn’t a gear, it’s one of those accessories which attaches to the hand. However, you may be interested to know that TakeoHonorable was hired awhile back to fix up old Roblox gears. How long it will take to go through them all is not something I’d know though, considering how long some of them take to fix.
