[Build Breaking] Some spirit reservation skills suddenly no longer useable

- Bug ref: 2,001,623,974
- 260 intelligence
- 367 unreserved spirit
- Skills used to work before, as I step into King of the Mist 2 arena I found that my cast on crit no longer work, finish the fight anyway, return to hideout to see that both gems are disabled and unable to be turned back on.
- Swap to second weapon set (The Burden of Shadow) allow Cast on Critical to be activated (Archmage is still disabled).
- Open Archmage detail panel and click on checkmark "Used with Weapon Set" activate Archmage for both weapon sets.
- "Used with Weapon Set" does not work for Cast on Critical.
- Issue persists through relaunches of the game.
- Hovering on the red exclamation mark of Cast on Critical says: "Missing socketed skill".

can you hover over the red explanation mark and post a screenshot please?

As requested:
Note: cutting new Cast on Critical allow the exact same setup to work, so what ever went wrong was specific to this gem I have.

There is an other solution, you can activate the socketed spell skills in it in both weapons slots and fixes it. Meaning click G expand the COC to the right, select Comet or whatever and activate it in both slots. For some reason, you can not activate it in only one weapon slot it has to be both.

I open the detail panel of CoC, select the Comet and DISABLE it for weapon set 2, this send me back to CoC detail panel with both weapon slots unchecked and the gem can be activated from skill menu again. So I guess workaround is found.
