Same happens to me. The only solution is to exit the game an relaunch your save. Then your units will reappear like magic...

Yes, same problem here.

I also reloaded the game. It was fine after the reload.

I also saw quite other glitches/bugs in this regard: Sometimes harbors turned invisible after one turn or two. Quite randomly after turn 300 (I tested the game only until Turn 400)

Hello, 

Would you have the diagnostic files of the game when those issues happened please?

They are stored in Documents>Humankind>Temporary Files

Thanks

@Kal didn´t you by accident hit the shift+ F10 ?

also I had the invisible army bug as well after continuing game after I won it. After changing civ it was fixed.

I reloaded my last manual save before turn 300 (See below). If you want to reproduce it, you only have to play the last 9 turns and play after the stats appears.

Here is the save: Turks Turn 291.ctr

Here is the save after Turn 300: Turks Turn 301 invisible units.ctr

Here a Screenshot: 

Here the Diagnostics (I ended the Turn 300 around 13:38/13:40:  Diagnostics_2021'08'20_@1320'29''592'''.html
