Thank you! In my case, I just adjusted the Cell Size in the World Settings (under the World Partition heading). Instead of 12800, I tried power of 2 values, and both 8192 and 16384 worked fine, so it’s strange that a smaller and larger number both worked. This also can solve the issue with landscape collision breaking after adding or removing components (however, this fix has not been tested in an actual build, just in-Editor).
