This is week 1 of an early access physics sandbox game, it is going to take way more than a single patch before things become noticeable stable. I have no clue what you were expecting for an early access of this game but this is what KSP1 was like when it was first released as well. The point is for those interested to get in while it is still being figured out, and help find weird bugs and guide the direction a bit. I am not expecting this to become a smooth polished experience for MONTHS much less within the first couple weeks
