As of right now, I have not had the required time to test all combinations of my mods, but I noticed that YnAMP was the most recently updated mod in my list and when I disabled the mod, the issue was resolved. Again, this may not be entirely a YnAMP issue, but could be a conflict with another mod, i'm still unsure. Anyway, on 3/5/2021, my two friends and I hadn't played civ in a few weeks, so we decided to start a new game. We chose to just play on a huge shuffle map, but when we loaded in, one out of the three of us (i'm pretty sure it was always one of my other two friends since I was the host), would spawn in and what they would see from the revealed tiles would be entirely different than what the other two of us would see. Example, I would see grassland tiles with iron and copper around their starting location, but on their screen they would be somewhere way off in the arctic regions with no resources or anything. The game would desync and attempt to fix the issue after each turn, but after my friend that was having the issue would load back in, they would see the correct land and resources, but desync every following turn. When we attempted to load back into the save (hoping that it was just an initialization issue), my friend would again see the arctic land. Sorry for the long post and thank you for any assistance.
