I made an era where it doubles the amount of units on the ground compared to the normal era. An XL/uber era. But I have this problem where all the props and I think character models fly around the map until finally making the game crash. Something I`ve also noticed that may be related to this is that some of the props far away from me seem to pop in and out of view.
Here`s a video I recorded to show whats happening, it went black because the game crashed -
