Unreal Engine Issues and Bug Tracker (UE-29651)

Description

Using a 'Format Text' node to set a 'Text Render' component will crash on map load after project conversion

[EUS] TJ Ballard - Opened the map on a users project from this AnswerHub post: https://answers.unrealengine.com/questions/406571/411-fatal-error-bad-name-index.html

User Description:

When attempting to load a map in my project, I'm given a fatal error which seems to be related to a single blueprint class.

When attempting to load a map in my project, I'm given a fatal error which seems to be related to a single blueprint class. Here's the full error message:

Fatal error: [Link Removed] [Line: 4384]
Bad name index 1110521144/225

I've included a minimal project which replicates the bug when opening Maps/MG_Garden. This error occurs on any release version of 4.11.

Another bug report seems to be having the same problem: https://answers.unrealengine.com/questions/397294/unable-to-start-project-after-411-upgrade.html

I've determined the cause to be with a Format Text node (highlighted below) being used in the Blueprint/Games/Minigolf/GolfStart Blueprint class' construction script.

Another user reporting a similar error but they stopped responding before it was resolved.

Steps to Reproduce

1. Open the attached test project in 4.11
2. In the Content Browser, double-click the 'MG_Garden' map to load it

Results: The editor will crash

Expected: For the map to load without issue like in 4.10.2

Note: Open the 'GolfStart' Construction Script bp to see the setup that is causing the issue.

If the 'Format Text' node is removed before project conversion, the crash does not occur.
