Weird, i though they are removed automatically.
Anyway, for 3 time there are 2 cases which can happen.
Imagine, i have 3 icons and type /icon then it shows
Icon A
Icon B
Icon C
Selected Icon is Icon A (the one which is displayed)
Case 1: Icon A is removed (case which you are talking about)
Then selected Icon is Hood, this is 100%
You can select next or random icon, wouldn't be bad
Case 2: Icon B is removed (what i mean)
It seems that selected Icon becomes Hood too even if Icon A is not touched
Why i think this is because i had Icon A selected and yesterday Icon B was removed but i still got Hood
