Summary:
- Changing function inputs/outputs in blueprints freezes the editor for over a minute and continuously increases memory usage.
- Compiling a blueprint takes longer and longer for each subsequent compile even if no changes were made. For example, one blueprint went from ~100ms compile to ~200ms, then ~400, then ~700ms, etc.
- The freezing resets after deleting the Intermediate directory, however, this does not fix the above issues.
- These issues seem to only affect blueprints of a certain type. Namely Actors, and Scene Components (possibly Actor Components, didn’t test). The issues are also shared between blueprints of the listed types. For example, compile times will increase across blueprints of the listed types. This hints at an issue with the parent classes.
Memory usage after changing a function input to array (blueprint editor window wouldn’t open):
Compile Time After no changes were made
Compiled immediately after. again no changes were made
