After the latest update on PS5, there is a bug with disappearing units in the game. Only their icons are visible. They just become invisible on the map (graphics bug?). This happens when the loads a  saved game ((it's random) . For this to work, I have to close the game and restart it.

I have newest patch v6.0.7.9-S10 BUILD 367354 ( or 1.002.000 on menu console)
