Hi,
I was going to update my maps but when I held it in my hands they start to update with corruption on them, corruption that aren't present.
In version 20w16a that there wasn't this issue.
Didn't do anything special.
EDIT : maps created in 20w17a doesn't appear to have this issue. But maps created in older version have this issue
