TFT Thieves Gloves Combine Bug
In TFT I had a one-star Qiyana on my board with Theifs Gloves equipped on her. I also had a Qiyana on my bench. Then in the carousel round I picked up a third Qiyana that had a Needlessly Large Rod. When the 3 Qiyanas combined. My Theifs Glove got thrown off the 2-star Qiyana and she was then equipped with only the Needlessly Large Rod, and the extra 2 item spaces were deemed unusable for the rest of the game. They were literally black boxes. I could only make an item out of the Needlessly Large Rod that came from the third Qiyana and could not equip any other items onto the 2-star Qiyana. Even after making her a 3-star the bug still persisted. I ended up losing the game due to the bug in a Ranked game.
In my opinion, if a combine like that happens in a game. The item with more value should stay on the 2-star unit after being combined, thus the Theifs Gloves should've stayed on the combined 2 Star Qiyana.
