[0.16.7-0.16.12] Random Desyncs

[mpease]

We have a server player (not headless) and two players in the same lan.
The server and the other player are playing on an nfs mount in the same lan with the non steam version.
I'm playing on my ssd with the steam version.
All systems are linux.

The map is very large and has a playtime with 167 hours.
The desyncs happens on random places and random actions.
If a desync occours every player except the server is desynced.

We think it happens more often if someone is near the spawn.
Or if someone gets items via drone and the inventory is full.

Sometimes i'm running between reconnecting so i stand on different places or have different items in the inventory.

Every desync report is found in here: https://m1.mpease.de/factorio_desyncs/
The last 8 reports are on version 0.16.8.
The other are from today (29.12.2017) are on version 0.16.7.

Maybe this bug report has the same reasons: viewtopic.php?f=7&t=55792

It should be fixed in 0.16.10, if not, let us know.

I still getting desyncs in 0.16.10 but now other players are not desyncing.

New reports are here:

At the moment of the desyncs I do a lot of deconstructing with the deconstruction planner.

Here are the latest desyncs from version 0.16.12.

https://m1.mpease.de/factorio_desyncs/0.16.12/

Things we noticed:
- The latest player that connects has the most desyncs.
- After we added another player (3 players + server) to the game all players except the server desynced.

Desyncs still occour in 0.16.15:

Do you know of any way to reproduce the desync other than just waiting?

[mpease]

No, but i think it has something to do with the spawn area. We bring a lot of stuff to this area and put it in logistic chests.
Maybe it occurs when multiple trains get unloaded but that are only guesses.

Its very hard to debug because it happens so randomly.
Last play was only two computers.

We also tested this on different computers so it must be something on this map.

We played today with version 0.16.18. Still desyncs. The second one is direct after joining.

I'm moving all desync reports prior 0.16.20 to resolved. If it still happens in 0.16.20, file a new bug report please.

[mpease]

Perfect,

we played today and the desyncs are gone.
