Hello Epic and to the Team, we’re happy that you guys have suddenly introduced us the bug reports topic and this threads too! I’ve got some and this is happening exclusively in Fortnite OG I suppose, and credits to AllyJax for the help too!
There's actually 3 items with incorrect attributes here still that Epic missed (also a math screwup on the AK's hotfix)
Heavy AR:
-Rare rarity is fine, due an error Epic/Legendary have FAR better spread than they are meant to. See clip for demonstration
Burst AR:
-Should have more crouching spread
-Should have more sprinting spread
-Should have less jumping spread
-Should have less recoil magnitude
-Should have MUCH faster recoil recovery
-Should have more recoil (ADS)
Minigun:
-Still has Per-Bullet-Spread, this attribute does not exist internally until Ch3S2
-Should have more recoil (vertical), less recoil (horizontal)
And listen, We all know this but.. OG S7's lighting is completely wrong, as S7 updates the lighting/sky DRASTICALLY
Here's comparison images on the current OG map!

Moreover, Lighting currently looks nothing like S7, before it was at least somewhat imitation. Legit had to rotate the entire skydome in OG for the third image to line up... Ik it’s not a big deal but still…
Please do NOT ignore these comments and/or reports, we’ll be happy if you guys will ever solve these issues happening in Fortnite OG currently. Thanks! :D
