Removing abyss socket suffix does not revert sockets to original number

What platform are you running Path of Building on?

Windows

What is the behaviour in-game?

Once abyssal socket suffix is removed from an item, the socket itself is removed from an item and its maximum number of sockets became default (4/6)

What is the behaviour in Path of Building?

Once Delve modifier (Has 1 Abyssal Socket (suffix)) is removed from an item (under modifiers section), links on the item remain as, for example, R-R-R A, which later triggers a warning if one places 4 gems into the given item.

How to reproduce the issue

1. Create a new item which can have abyssal socket (armor piece)
2. Click 'Add Modifier', select 'Delve' and Has 1 Abyssal Socket (suffix) mod
3. Click 'Add'
4. Once added, click 'Remove' against added modifier

Expected:
Sockets revert to original (i.e. R-R-R-R)

Actual:
Abyssal socket is still applied (so it is still R-R-R A)

記載されているmodifierの手順とリンク先のTitan Greaves buildを使って問題を再現し、その後、Delve modifierを削除するとアイテムのsocketがどのように更新されるかを追跡します。abyssal socketが削除され、警告を発生させることなくアイテムが元のsocket数とlinkに戻れば完了です。
