Invalid Index {%d} while resolving compiled property chain

Has anyone faced issues with the Chooser plugin in Packaged Builds? My setup selects animations based on Tags. It works fine in PIE, but in a Development Build, it starts throwing errors and—worse—selects animations even when the corresponding Tag is missing.
It feels like the property bindings or indices are getting messed up during cooking. Does anyone know how to debug which binding is breaking, or how to fix this discrepancy?

Looks like it was a Property Access binding issue. I just re-linked the variable and it’s fixed now.

By the way, I also disabled the Editor-Version binding to debug it. It’s really confusing that there are different implementations for the Editor vs. Packaged builds. Is this intended, or does Epic plan to fix this later?

ps: the problem is still there, I rebind the property,and it works well in the editor, but it apears again after i packaged the project, the problem comes with tagquery column

Did you manage to solve the problem?

So far it looks “fixed.” I disabled CompiledPropertyChain (commented out the logic around bUseCompiledChain) and switched to the same property-access approach the editor uses. From what I’ve seen in the Shipping build, everything works fine. I haven’t benchmarked the performance difference, but in my experience there’s practically no noticeable difference.
