I have the same problem. (Since 0.4.0.0 and still on 0.4.0.1)
I did a several tests on Suite and Art Studio in singleplayer mode. So far it always freezes on Suite usually under 3 minutes. Even when it's empty and I'm not doing anything (not even moving). However so far there was not a single freeze on Art Studio.
Did anyone else experience a freeze in Art Studio so far?
