Apr 1, 2024April 2024 — SecondLife Viewer: Delivered a reliability improvement for model loading by refactoring FindModel to return a boolean indicating success or failure and propagating the new return value across the codebase. This enhanced error handling and robustness of model retrieval, directly addressing the BugSplat crash 1412267 caused by a missed refactor. Result: more stable asset loading, fewer user-reported failures, and a cleaner error reporting path.
