Known Bugs And How To Fix Them

Known Bugs in UI3 and possible solutions. This may require editing some blueprints or widgets.

Some things are easy to fix if you do not want to wait for an update, or if you do not want to risk your work is being lost because of an update.

Problem and Cause

Only the Features are exported into the user's Google Sheet.

The widget UI3_MainMenu_GS might have the wrong GID variables connected.

Fix

Open the widget and navigate to the Graph window. Look at the 2 areas at the very bottom. Check if the GID's for Selections GID and Features GID are used. There might be the Costs GID variable connected instead.

Drag the replacement variables from the Main Menu pin. Compile and Save.

This only affects packaging, not playing in editor.

There are three widgets that need to be recompiled and saved. Nothing needs to be changed. The files are in UI/Widget

• UI3_ButtonIcon
• UI3_ButtonText
• UI3_ButtonWithText

Fixed in version 2026-04.2

Bug

The mesh disappears when linked to the Variation Actor or the Mesh Variation Type is set to other than Disabled.

This is because the Actor World Transform isn't set in the variation actor. The mesh is therefor moved to position 0,0,0.

Work Around

Copy the mesh's Transform into the variation actor's Actor World Transform before linking the mesh to the variation actor.
