Recently i noticed this mod has a combability issue with space exploration. this first appeared on version 0.6.81 of space exploration but also was able to be reproduced with version 0.6.80, there team said the desync is caused by belt balancer and is somewhat inconsistent as sometimes it happens and sometimes not, apparently it all depends if the first time connecting causes a desync or not, every connecting afterwards will produce the same result.
For context i will reference this thread about the issue: https://github.com/EarendelDevelopers/factorio-mods/issues/226
