Is this using a non blocking save?

Can confirm this is the case. The effect in single player is that it will create a character corpse, if you use index 0 (remember lua is 1 based indexing) it will create a I_IBlackI_I corpse.

I would also love this feature, or make tags on a minimap element clickable. Use case would be to draw a map with locations on another surface, when a player clicks the tag they can teleport to that server.

An alternative to this is to make a player in god mode and adjust the game.player.zoom (http://lua-api.factorio.com/latest/LuaP ... layer.zoom). This way it will also show the GUI for the spectator to interact with.

This has been known to present issues like a lot of other entities. (e.g. belts and walls), sadly they told us last time this is a won't fix. Can't find the topic anymore however.

Possibly fixed in 0.16.30? https://www.reddit.com/r/factorio/comme ... ion_01630/

Looks like this is a game using my codebase which can be found here: https://github.com/factoriommo/factoriommoscenarios/tree/0.16_Dev It is known that Factorio still has desync bugs related to ghosts on different forces. Not sure if that is the case here but I do see you have ghosts enabled. We hav...

This specific occurrence has not been recreated, however there are still quite a few desyncs which only occur when we got the part of our code which creates a ghost on another force when a player destroys(mines) active. We have been investigating the desync reports as much as we can but we have not ...

Sadly I again was not there when (a similar) issue occurred.
It instantly desynced on join.

Here is the folder with all the new data. (Currently uploading but should be complete in 40 minutes)

Yeah no problem, we always try and supply you with as much information as we can. Will update if same issue occurs.

Our scenario does not set an entity active true/false directly. But it does create a ghost on an other force when a player mines an entity. Could that affect it?

When restarting the server the issue did not occur again yet.
The map was a fresh 0.16 map with our (very dumbed down) scenario.

I was not around when the problem started occuring, but others have suggested it may be because commands were run from console while there were no players online.

When connecting to the server anyone instantly desyncs.
Save-file(s), log(s) and heavy-mode(about 4gb but containing multiple ticks and join attempts) dumps can be found here (soon(tm)):

Restarting the server did resolve the issue.

Loewchen the issue is very clear and easy to replicate, as twinsen said it is a bug and should be reported. Steps to replicate: Place 3 belts in a L shape. Switch forces Place a ghost belt against the L shape making it a ┴ shape. Switch back to the previous force The belts now look like they shouldn...

Here are two of the desyncs differences. https://imgur.com/a/Gm8wQ

Relevant thread https://forums.factorio.com/viewtopic.php?f=7&t=45590&p=262391#p262367. In this thread the value being different between client and server was global.player_spectator_character this time it is spectator_character (we updated our code a bit) 8 months later and the same problem...

Would trying to get this error to occur while running heavy mode help you?

Yeah I guess that doesn't count as a crash. When you are playing a game on a server and you suddenly lose connection / server stops responding most people assume it crashed instead of gracefully shut down because it encountered an error.
Apologies.
