Apology Weekend
From Growtopia
Apology Weekend was an event set up to apologize to everyone who had lost their belongings to the rollback. People had a higher chance to get more gems, items, and seeds from blocks. When players break blocks, sometimes a red flash would appear on the block, signifying a lucky drop of gems, the item's seed, and the item itself. The limited Rollback Plaque was also available during this time.
A second Apology Weekend occurred between October 5th and October 7th due to another rollback. It had similar benefits to the first Apology Weekend, except you were not able to craft Rollback Plaques. You could instead craft Rollback Plaque IIs.
Bonus drops are highlighted by a red flash when you break a block.
