Multiplayer game freezes randomly either for host or for the other player

Description
Every now and then after playing for a while it would seem either me hosting or my friend game would freeze. Music still plays, UI doesn't respond, and simulation stops for the not frozen player. If the frozen player is the host no savegame seems to be created automatically(we had this overall issue at least 7 times yesterday, it did create the savegame on 1 occasion when the host was the one freezing).
No particular action seemed to trigger it, but it would seem it happened after "doing" some action, be it pressing v to switch the unit or group view, g to group some units, or overall interacting with the game at the very moment it happened, not just looking at the game if that makes sense.

The scenario was built with the help of AI and lua scripting, at first we had it with custom scripts for replenishing ammo trucks from main ammo depots and to be able to capture airfields+planes and enemy ammo depots as recurring events. We removed those and gave it a fresh try too but we still had the issue. The only other script we had was a scoring one to add or subtract equivalent points based on losses. We never got to remove this one due to lack of time to play.

We also tried having my friend host the game to no avail, either him or me would still get the random frozen state

Frequency
Quite often, once every 5-15 minutes

Steps to Reproduce

Unsure, but on the first oldest save we had that freeze on the non-host player. I reloaded the multiplayer lobby with the save, my game froze immediately after pressing play and the 2nd save got created when I closed my game with apparently 6 seconds of simulation later. We both restarted our games, closed and opened them fully, reloaded the very first save, it worked until the 3rd autosave freeze. So it might indicate that closing and re-opening the game reduces the frequency of the freezes.

I always played as belgium and my friend as the netherlands.

Attached Files
-Multiplayer saves.rar All the sequential saves we made trying to keep playing and debugging this.
-Logs.rar both exception logs and lua history file of the scripts used when creating the scenario. My friend's exception log is not complete but it's the one I've got from when he sent it to me mid-debugging, at that point he already experience his first freeze and that's why he sent it to me.



Additional Notes
Having the ability to save manually while paused and not only when one player leaves the session would be great. Or being able to have autosaves during the game would be even better.
We're not sure if the number of units could be a factor.
We have not tested other scenarios yet, we couldn't find any on the workshop that were labeled as multiplayer and we don't know if any of the vanilla ones are mp compatible. We'll try some other simpler scenario when we have time.
Hope this all helps somehow, and keep up the good work! this multiplayer mode has a lot of potential.
