That is super unfortunate to hear. I would wager that most of the dedicated servers running factorio are linux, and as the saves get bigger the process takes longer. When you mix in mods with that you have the possibility of the mods crashing the server, so you want to save frequently, but if you have blocking saving you spend as much time saving as you do playing.
So then if you start saving say once an hour instead, you risk a huge setback from a crash.
Certainly sad news if it gets pulled.
Is there anything we (the players) can do to help you guys to keep this feature?
