Adding the HISM Actor set tag to an array (or same with Actors of Class), when checking the array as invalid/empty - we never get a boole change when the array has nothing left in it.
Not sure this is a bug, but this seems like not proper behavior.
Basically, need to know when the HISM actor go bye bye. Tried using both Get/Invalid and Length/=<0 array where again, the boole does not change when the arrays are empty/0.
This means HISMs can be decor, and it can be BPd to do things - but it can’t be a pick-up nor enemy, nor anything that needs to be accounted for when it is destroyed.
Thanks for the report - In researching this issue I’ve came across a couple of threads that seem similar to what you’re describing. (Specifically weirdness with changing arrays of HISM actors)
I’m unsure if HISMs were intended to have functionality beyond foliage/decor.
If you’d like me to enter a bug report please provide a list of repro steps or sample project.
