As noted it's a beta. It's going to be a smaller player base than the real game, and there's going to be technical issues that you're going to run into which is the point we want you to run into technical issues so that you can tell us about them.
The trouble is a lot of developers use the word "beta" to mean "demo". This is a beta, it's not a complete working game.
Please do not play it if you expect a complete and working game.
In the future I'd suggest not playing one of our betas if it's going to upset you because it's a beta. We'd rather you wait for the complete game and make your judgments from that. The final game will be a more complete experience, with a larger player pool and viewer technical issues because they've been uncovered by the helpful people in the beta.
Btw Noun, loading games make my game crash don't know if it's a known issue or just an issue for me.
