France here, same thing. 2x a day crashing. I cant tell if this is machine-related or just early access related. The instability has also cause some progress loss for my group. I am wondering if it may be like minecraft, where, the more entities there are cluttering up the world, the more strain it puts on the server, but the cpu usage and memory usage do not appear to support that hypothesis.
UPDATE: However, some users have noted (See this thread:
) that the instability only became a real problem after the 10/2/2021 update. But the dates of these posts suggest otherwise.
