Factorio Forums

I'm not sure how it is related, but the game crashed right when my host earned the 'Mass Production 3 achievement'.
We were only two on the server, and he could keep playing.

When the crash occurred, I just ordered deconstruction of a reasonable area, about 10*50 tiles containing mostly steel tanks, pipes, pipes to ground and pumps.

Autosave a few minutes prior to the crash can be found here

, and attached is my logfile.

Hope this helps you find and fix some obscure bug.

It crashed trying to read a heartbeat packet from the server that should never have been sent from the server without at least 1 mod installed. That sounds like the packet was corrupt somewhere between the server and you or was corrupt after being parsed from the network on your computer.

Have you been having any "random" issues with your computer? Has this ever happened before?

No, This happened only the one time.
Most of the time Factorio runs fine, and I haven't noticed anything weird happening on my computer.

In that case, I would put it to pending.
