trying to make out this desync issue

so i pretty much always desync when i get into a game online game, i recently i got a new router and modem to see if that would help, sadly it did not.  so today me and some friends started up a game to try and see when the game starts to tweek out. i picked advent rebels and they picked tec rebels game starts and my friend starts his timer

 it turns out not very long at all, we noticed it desynced within the first minute or two, and seemed that it was triggered after a certain amount of frigates were made, we each started making our starting units i made 5 LF's and my other friends made 6 and 7 frigates and told them to go do something, but i was only able to see 5 of the frigates they made do the action, the other one or 2 would just sit at the spawn. this did not happen to the cap ships however they each when ever we told our  capships to do something we would be able to see both the flagship and free cap do those actions.

after that basically anything we did wouldn't happen and the ai controlling us would just sit there until i think it fully desynced which then the ai would kick in completely

thats just from what i observed so gonna go try and few more things later and il remember to record it this time( i keep forgetting that this game has that feature....), its so hard to tell what the fucks actually going on 

EDIT

also forgot to mention between any sort of giving of materials, missions, building of buildings or adding bounty did not fall out of sync for anyone.
