When you host, Blockland always freezes when the first person connects. I guess this is because your server doesn't upload the files into it's cloud until someone connects. I don't mind it, except that people are impatient and disconnect while it's frozen for 10 seconds. I wish there was a way to to regenerate the file manifest manually.
Lock: Just tried being on the client side of the first connection. There is absolutely nothing that happens that would make me wanna quit; it's just handicapped people leaving as soon as they join.
