[0.11.5][kovarex] Multiplayer Desync Loop, since 0.11.3

[Fatmice]

Hello Factorio Devs,

Attached is a 102+ hour multiplayer game that I played with a friend. We experienced multiple desync loops that were recoverable during various points during the game via various voodoo magic/shenanigans/tips found on forum. The most recent desync loop was not recoverable for a long time. I had tried many things. In the most recent alpha release, I ran out of options so finally I shutdown all subsystems in our base, removed all drones, and be stilled all manufacturing. I waited for at least 5 minutes after everything is still and killed all the bitters with the command /c game.killallenemies() before my friend joined. My friend was able to join and we did not go into desync loop. I'm still trying to figure out why it worked and what exact thing/machine that caused this latest desync loop. So far though, either killing the power to the base, minus power to peripheral laser defenses, or stop all manufacturing seemed to allow us to recover from the desync loop.

Simply loading the old save game from 0.11.3 into 0.11.5 did not make the desync go away.

MP-012.zip has the desync loop.
MP-014.zip is where desync loop was resolved with stopping all material processing, no inserter movements, no active manufacturing.

Hello, thank you for the save, I investigated it, and found out a desync problem related to pollution spreading. It will is fixed for 0.11.6 now.

Thank you for your hard work. What can we do in the mean time? Spread out our manufacturing so the pollution value is smaller and negate it with many many trees? A part of our base is very productive, but very very dirty/polluting.
