Message saying "Deep Dive" contains an inappropriate word

[Finix]

I was building the “Deep Dive” card deck. When I tried to name the card deck, it said “The name contains an inappropriate word”. How “Deep Dive” is an inappropriate word?

I’m betting it’s the spacebar.

[Duhos]

it depends on where you diving in ._.

Yeah the spacebar is a restricted character for pretty much everything. I can’t even name my “Eiburn’s Wound” ship to “Eiburtle Wound” (since it uses the turtle skin), yet the default name has a space in it!
