ZMP Desync when spawning massive amounts of items #26

Open TurkeyKittin opened 3 years ago

TurkeyKittin commented 3 years ago

Originally identified when spawning certain items with mods, I realized this was happening in general in ZMP+RC play too.

When a server is started with the arbiter running and wait for arbiter to join... Everytime a weapon is dropped, there is a small chance for it to cause a desync. This was not reliably reproducible until I started spawning in many quality oriented items.

First identified when spawning 100x longswords. It was getting reproduced reliably until I full restarted my Rimworld game.

I tried spawning in 100x random weapons via vote 3 times. I tried spawning in 100x random apparel via vote 4 times. I tried spawning in 100x longswords via vote 6 times. I tried spawning in 100x sniper rifles 1 time via vote and immediately got a desync.

The next time I started a new colony and I tried spawning 100x longswords via vote , immediate desync again. Tried the same thing again in a new colony, desync on first 100x longsword drop via vote.

Did a full restart of the game.

Tried to spawn 100x longswords again via vote and immediately got a desync.

Modlist load order:

Harmony Core Multiplayer RimConnect

I will likely continue testing this and report more findings.

The following are 4 instances of the desync tick in separate save games.

Currently even having it desync on spawning 100 gold in a vote.

InfinitySamurai commented 3 years ago

Damn on 100 gold too? I was thinking there was something about the way that item quality was being assigned. I know there are some items that spawn really strangely from the random weapon event (#20) but on something as mundane as gold is really weird.

TurkeyKittin commented 3 years ago

Yeah I was confused by this too, but it seems like it could be a sort of cascading failure where it fails once and affects all calls afterwards unless you do a full restart of the game. I'm not sure if I'll have time to test this idea today but it's worth a shot.
