Keep being desynced from a server

[zarte13]

Hello,
My friend and I were playing on his dedicated server and all the sudden we get both desynced.
He tried to reboot the server still did the same thing
Additional notes: we were playing on the latest version of Factorio 0.13.1
We were just the 2 of us
Here is the link to the whole desync report: https://www.dropbox.com/s/dp2b9cud2ann2 ... 9.zip?dl=1
Going also to add the just the desync log file as an attachement
Thanks in advance
