I updated two of my worlds this week (commencing June 3rd), but the Last Update line in the world info is still showing a date from last month.

World IDs:

wrld_9a201168-7839-45b5-a391-5ef6ea1473f7

wrld_97c0775c-902b-4f40-893c-d8b865499414

Also, for the last few days the Recently Updated world list in the menu is only showing a handful of worlds (and not mine, since the date is wrong). The section is also missing from the website, maybe that's intentional though.
