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)

Reproduce the issue using the listed modifier steps and the linked Titan Greaves build, then trace how removing the Delve modifier updates the item's sockets. Done means the abyssal socket is removed and the item returns to its original socket count and links without triggering a warning.
