also having this exact same issue. My minimap was working fine, then I updated it and now it’s having issues matching my player position. If I update the camera every frame I can see my projectiles in the proper position, but the blue dot on the minimap is off by a bit.
It seems to only happen on the X axis, and if X=0 then it’s bang on. but if I go over to X=10,000 or -10,000 it’s off by quite a bit. Something up with this update. Anything I draw on the map is off, not just my local player. I have flags, enemies, etc that I draw on my map and they’re all off.
It’s probably an issue with the “Event Driven Loader” that Epic enabled by default now even though it still has quite a few bugs. Can you try to disable that and see if it fixes the issue?
