Factorio Forums

I'm encountering a bug where a connecting player can't sync after a certain event. Unfortunately, the event caused the game to freeze (would accept console menu opens, but no commands and nothing else even opened, not even the exit menu).

The first event happened sometime around the creation of a very large blueprint by my friend, and the game completely stopped - nothing responding, had to close the game manually. After that point, whenever I hosted the same world the following events happened in sequence:
-1: Friend connects.
-2: Map is sent to friend's client.
-3: Friend gets in and then immediately desyncs.
-4: Steps 2 and 3 repeat infinitely.
I created a brand-new world and he was able to join without an issue - same with loading an hour old save.
Interestingly, after an attempt to load one of the autosaves, Factorio crashed after I exited to the menu.
Will PM save link to devs if requested.
I have a suspicion this may have something to do with some sort of unchecked limit on the size of a blueprint causing some sort of error and failing to sync the entire thing, causing an error resulting in it all starting over again.

I have the same repeating steps 1 - 4 as well but does not seem to be caused by an event or specific action (at least one I have been able to determine.)

I can add the following:

• Same map single player works with out issue
• Doesn't matter who hosts the map, the remote player desyncs instantly on joining
• Previous version of the same we played together without issue - only minor changes since (small amount of rail, one 2 car train, and a few pump jacks into 4 tanks of oil)
• Removing those changes now, has no effect
• Same problem exists with 0.11.3

Hello, there are lot of synchronisation bugfixes prepared for 0.11.4 so I'm moving this to resolved for next release, as it is most probably related to this one as well.
