On the reverse iteration, yes that’s what I meant when I said the adds would be skipped for the current iteration. That IS okay for my specific case, but maybe there is an issue for others? Not sure.

I do see where you have protection in ActivateAbility while processing an update, so I started digging into the issue all the way through the stack and found the issue. I added a picture of where the problem is. It’s in the ActivateAbility IsNetworked() block when the game IS authoritative. There is no IsProcessingUpdate check.

On a completely unrelated topic (or two), is there a reason you chose to make this an engine plugin instead of a project plugin?

Also, I know you like data driven design, so I was curious why your AI tasks take an explicit ability reference rather than using a FBlackboardKeySelector to get the ability from the blackboard. I actually modified several of the AI tasks to use the BB and it works out nicer for my case. I have a shared Attack tree that just plays whatever Ability is on the blackboard for the AI using the tree. That lets me put data in a data table and push it to the BB.

Yea, I think I’d prefer to have it delay the application of the new abilities till the next frame during an update. And yes, that line is the offending line. It should check if we’re in the middle of processing an update and defer like the non-authoritative logic does above it. I’ll get in a fix this weekend.

As for the Engine Plugin vs Project Plugin, UE tends to play nicer with Engine Plugins in my experience. That’s the only reason.The AI feedback is really good, I’ll look into adding that rather than the explicit version (or give you an option for either - I can see use cases for both).
