Regression: MakeLiteral GameplayTagContainer fails to match GameplayTag queries involving parent tags in 4.17.2 vs. 4.16.3.
I have identical "Has Tag" queries in 4.16.3 and 4.17.2 that return different values. I do not have the easy ability to compare 4.17.1 to these two versions. I have minimal repro projects for these two versions.
In TestTag, in event graph:
Next in the event graph, to confirm the error:
In 4.16.3, a similar project had both cases return the expected value of true.
This is really fundamental to tags! So much so that I'm surprised to not see anything on this - thus a pretty rigorous testing setup. In my main project, it looks to be even stranger - for instance, when I used the Tag AssetInterface calls, I got spurious results that seemed to sometimes be true or false in between loads without a Make Literal involved. No minimal repro case on that, but FYI to whomever fixes this that there were some other apparent instabilities in results. I'd suspect that the call on gameplay tag containers that populates the parent tags isn't happening properly on MakeLiteral and/or some other cases.
If a repro project is needed, let me know- -jg

Any followup on this? It causes a variety of subtle bugs when using Gameplay Tags; we're hoping it is fixed in 4.18. Thanks!
