Factorio Multiplayer DeSync on Tank Entry

[Phantum]

So a buddy trying to connect to my server, gets desync'd When using a tank to clear out biter nests. It the southernmost part, with the Label of Bacon Tank Crash here.


Here is my current Log, along with the zip of all used mods, and a copy of my savegame as well.

(what ever you do, it is inadvisable, to take apart the Horse armor DLC (it's an insider joke, Ask rseding about it)

Post the desync report, see my signature.
Can you reliably reproduce the desync? If so please provide the exact steps.

It was something to do with RSO, we downgraded back to 3.0.0 version of RSO and the issue went away. Already sent the mod author this link.

However, here it is: https://www.dropbox.com/s/dfacdieapq846 ... 1.zip?dl=0

Did this desync repeat?

Main changes to RSO were to add settings and usage of in game built in random generator. So I'm at a loss at what could have caused the desync.
I tried looking at diff between level with tags but it looks like almost everything is different.

If desync repeats maybe devs can help. If not then it will be tricky to find out whats going on and I might need to go back to lua rng and see if that helps.

The built in Lua RNG uses the same RNG that the game does so it shouldn't be a problem. It may be related to the reactors desync and restarting the server helped it (since it's a save/load stability problem) - but that one should be fixed in 0.15.6.

Hmm, actually the desync looks pretty clean.

Is there any chance someone was building rails at the time it desynced? Using the rail-planner?

When I looked at differences there was a ton of rail ones.. I'd expect more of ore ones if RSO lead to desync.

I never dsync'd as I was the host, I'll ask my viewers to send me their dsync logs if they're able

nah, I was in our base, (which was sorta close to our nuke reactor) and Thillthecool was riding around in a tank, the moment he explored a new section it desync'd him and another of my viewers, I'll go through my video tonight and highlight it for you guys to see what happened (it was map view so I can't see exactly what he was doing unfortunatley)


Edit: https://www.twitch.tv/videos/139716379 sorry, it's a bit long and its not the best showcasing of it. A bunch of stuff can be skipped through.

Thanks for the report. This should be fixed for the next version of 0.15.

No worries buddy, as soon as I can get ahold of the other dudes I'll get their dsync logs uploaded for you guys and Orzelek just to be sure!

Edit: yup, no Dsync's with latest version of RSO, and .15.6
