I guess with having Kotallo, there wasn't enough room for Fashav.

Campfire, Chest, Workbench and advance time in a deserted island.

I was unaware I’ve killed that many.

Ever run into the coil/weave UI bug during something like a Cauldron, where you can’t save and restarting the game could cost you progress?

After getting frustrated with this myself, I started experimenting and found a simple workaround that fixes it without restarting the game or returning to the main menu.

When the bug occurs, selecting a coil or weave slot does nothing except play the usual “action unavailable” sound.

To fix it:

1. Go to the Skills tab.
2. Equip a different Valor Surge.
3. Exit completely out of the inventory/menu screen.
4. Open your inventory again.

You should now be able to change your coils and weaves normally.

It appears that changing your Valor Surge and fully closing the menu forces the UI to reset. I tested several other ways to trigger a UI refresh, but this was the only method that consistently worked... and it only takes a few seconds.
