If you're having technical difficulties with Orchi, you can post about them on this thread.
Check these common 'errors' and how to fix them first, though.

> The game crashes/breaks when entering character select
- clear character cache through options > delete character cache
> Character is grayed out in character select
- your opponent doesn't have Orchi, or one of you has an outdated version of her
> Is my Orchi outdated? Theres moves missing, but I'm subscribed to this workshop file!
- close game, resubscribe and try again. there's currently a workshop bug that doesn't always update the character.
