Are there time limits for Pantheon of Builders submissions?

I was wondering if there is a time bracket/limit for Pantheon of Builders submissions, or if there are brackets/waves of pantheon showcases (ie. once per month)?

'cause there is a bug right now that makes some of my best bases unload-able (this is already reported in bug section by other players), but it means I won't be able to polish and submit them until bug is resolved.

If so, can we pls get a time extension until the error-base bug is fixed?
