Nick thank you for the comprehensive response, it sounds like those changes are the likely culprit.
The EventTick only seems to be called when the scoreboard is being shown by the player so I guess I am ok with a quick and dirty solution using ForceLayoutPrepass which works for now.
Ideally ScrollBox could mature to use a pool of widgets somewhat similar to how UITableView works with UITableViewCells in Apple’s Cocoa Touch framework. Do you think we could see the ability to set a custom widget and a pool count on a ScrollBox? Or do you think that is too niche of an application?
