I've encountered a bug and I need help!

New Zealand time, around 3:00 a.m. on Wednesday, May 21, 2025, I encountered a serious bug in the game. I was crafting an item in my inventory, and the signs of using an invalid stone and using it twice appeared. However, after using the invalid stone, only the sign of the invalid stone suffix came into effect, while the sign of using it twice remained in my inventory. The change to the equipment was that one prefix and one suffix were removed. I'm absolutely certain that my operation was not wrong. All the signs were in the activated state and I checked it many times. This bug is really bothering me! I will keep the faulty equipment in the storage room. If possible, I hope you can verify it and help me. Thank you!!!
