[17.21] Desync on 2nd connection

[KingPin]

hi, I am using a few mods predominantly Bob/Angel and factorissmo2 along with squeak through, RSO etc.
since 17.16 ( - 17.21) I am getting a desync on the second connection to the server, it can be the first player logging out and logging back in or a different player trying to login and I get the same result. I have debugged by removing plugins and testing and only one that fixes it is removing factorissmo2.

I have been researching how to debug this on discord + google & reddit for past few days but figuring out how to fix desync seems to be, find mod causing desync => remove mod => profit. which doesnt work here because removing factorissmo kills 80% of my factories.

The machine is a beefy dual E5 Xeon with 64 gigs of ram and a gigabit connect so keeping up with factorio shouldn't be an issue.

Any help is appreciated. thank you.
