It seems this report is about the same issue: My map "broke" after today update
This is kind of a blocker for me, because now my island is way over the limit AND streaming/LOD seem completely broken, making memory optimization unreliable or useless.
I also have before and after private island codes I could share, which show the sudden change in behavior and memory usage, with the only major change being upgrading to 25.10.
Any help would be appreciated.
