My equipment inventory was changed after changing class

Happy evening, about 30 minutes ago I made a class change, specifically from Arcanist to Blood Knight, but after making the change an incredibly bad error occurred and that is that 4 set pieces that I had in my inventory changed and became the same weapons that I had equipped, losing my original equipment with more IC, infernal magic, vanguard boss skills, etc. what should i do? I need to recover my equipment, we are talking about half of my set, I don’t know if it is a bug or an error in the game but do you know how many weeks of farming and money it takes to get that level of equipment to lose it just like that? I need a quick solution, it cannot be possible that now even having things in the inventory is not safe, where should they be stored then? I am quite frustrated and angry, so I sincerely hope that this is resolved soon and quickly.
In addition to a description of the bug you are reporting, please provide:

Device Type: Xiaomi
Device Model: Redmi 10pro
Device Operating System: MIUI 14.0.8 wih android 13
Diablo Immortal App Version: 3.1.1

are you saying that the greens in your inventory switched stats to match with your new class? So would they not possibly switch back if you went back to the previous class? If its even supposed to work that way lol

No, I’m talking about the red set, before the class change I changed 4 pieces so that they were duplicated and I could equip them with my main class (because they came out while farming with the wizard) but instead of being duplicated, they overlapped with 4 of my pieces of main equipment that were in the inventory, so I lost my main equipment and only the duplicate equipment remains, that’s why I’m worried since I lost a lot of IC, infernal magic and vanguard skills that were in my main equipment
