Hello,
A friend and I playing MP on a dedicated server. We first played Vanilla to get some achievements, but now we added some mods.
We found that every time my friend opens the hellmod UI I get desynced for the server.
I also get desynced when open the UI myself.

Desync reports:

Edit: Also on 0.17.9

I have the same issue in mp. Version 0.17.9

We are seeing the same issue. In my example, the game seems to have suddenly added a new production line that I had never planned (locomotives?).

This mod was stable until we both jumped into a single player creative world, and unlocked everything. Sounds like some achievements might be causing issues?

Playing on 0.17.11, dedicated server as well.

Clearing achievements and rejoining didn't seem to correct anything, so i don't think it's related to that. We tried to enable debug, but got the following after setting the helmod logging to anything other than none:

25116.571 Script @helmod/core/logging.lua:80: [ERROR]|HMPlayer|"settings property not found:""debug"

Still no fix? :(

try using optimized version this mod https://mods.factorio.com/mod/helmod-optimized

Thanks for tip, i did try it out but i got desynced even playing alone in the server.
First time it didn't desync. I was able to fiddle with recipes. Then i quit game and came back after a while and opened up the optimized helmod with my recipes still open, and it desynced instantly.

Same desync issues with us. Optimizing the mod doesn't seem to be the issue. Factorio should handle hangs gracefully. Something in the mod is non-deterministic.

Hello i'm tested on your mods and your save in new version mod don't have error with desynced
Try helmod-optimized

This version of the mod actually desyncs more often for us than the un-optimized version. Granted, small data set of tests so far today, but it clearly doesn't fix the issue.

Edit: 0.8.4 was tested, will try the newest version.

I know there is a problem of desync.
before seeing this bug I started to modify in depth, this takes a lot of time. to be patient

The 0.8.5 version of the optomised version works wonderfully. No more desyncs!

Fixed in Version 0.8.4

Sorry to say, but we still have desyncs. :/
If you need logs or something i would be glad to provide them.

arf yes can you give me log of desync

Try v0.8.5
I have tested:
player 1 host game and use helmod
player 2 join after and use helmod
there aren't desync

Do you can write fix for 0.16? Very very please
