Literally one of the best mods I've found on the workshop, a great mixture of amazing ideas and execution to make for a real challenge! However, as much as I love the mod, compiling it with my private multiplayer packs I play with my friends causes a lot of trouble and I'm looking for some help fixing these problems. Here's my analysis:

Modpack A - Has a bunch of mods, adding various civs, textures, buildings, tech tree modifications, etc. I can be more specific but it's a long list.
Modpack B - Has the same exact mods as modpack A, but also includes Barbarians Evolved v5
Desync - When all players are forced back to the loading screen into the game

Both Modpack A and B were compiled with https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=361391109, a multiplayer mod workaround created by the people over at civfanatics.com

Test 1:
i) Load up modpack A
ii) Play for about 50-60 turns
iii) Save game
iv) Reload game (with same players and mods)
v) Play another 10 turns, no problems!
Test 2:
i) Load up modpack B
ii) Play for about 50-60 turns(no problems here! barbarians make it a challenge to survive but thats the point)
iii) Save game
iv) Reload game (again with the same players and mods)
v) Play about 2 more turns before a desync occurs, and then another desync occurs about every 1-2 turns afterwards

I repeated Test 1 and Test 2 twice on different maps to make sure they weren't anomalies. I'm very new to the modding scene, but I want to contribute and make my own multiplayer packs. Perhaps the mod author could key me in to why I'm getting these desyncs or how to fix them.
