Sent a ticket, and got a response from EdgeWater telling me to post my problem here.
I have a level 95 Barbarian who just got a homestead the other day. As with all my characters, I expected to get some crops and a charter to expand my plot, but those didn't drop into my inventory, which indeed did have enough space.
I'm pretty sure I cleared the tutorials sufficiently. Thoroughly went through construction, codex and the resource buildings looking for anything I might've missed. Alas, nothing. =(
