To be clear, support has been wrong in the past. However, your screenshot does prove nothing. I’ll explain why it proves nothing below.
From my experience with Wayland’s mod box, it was 100% a visual error. The visual error showed that the mod, that you got from Wayland’s box, is the exactly the same mod that you got prior to Wayland’s box.
Eg: I opened a platinum mod box from SR and I got a defense set Graze mod. Then, I opened Wayland’s mod box and chose a crit set, but the visual error showed that I got the same defense set Graze mod from Wayland’s box.
If I go into my mod inventory, I have two platinum mods labeled new: A defense set Graze mod, and a crit set mod.
The reason why I say your screenshot proves nothing is because with the visual error, it shows that you got a crit set “Attack vs Fast” mod. You actually got a different mod, but its visually showing your last obtained mod. When you look in your mod inventory, you don’t think it is a visual error because you see a crit set “Attack vs Fast” mod. That mod was already previously obtained by you, so it makes sense that you see that mod in your inventory. What you’re missing is the mod that you chose, but aren’t able to identify because of the visual error.
The only way to identify what mod you actually got is when you open the mod inventory and see the “New” tag under the mod. Unfortunately, that tag goes away after you close out of the mod inventory for the first time after getting that new mod.
