That clears it up a bit. May I suggest hiding these when they are not relevant? (one animation and no dynamic montage respectively). There is no mentioning of this in your manual for non-coders like myself.
Unfortunately just saying “it works” didn’t fix the problem on my side. This issue occurs in ~20-30% of cases after working heavily with the ability for a while. I’ll try to make a video next time I’ll catch it. The case with montage however is 100% reproducible all the time. Please address this issue as it is very annoying to always switch back and forth to Single Node mode just to test changes.
An error sounds more like an informed way to solve and find issues to me, so that would be helpful indeed. As for the pin disconnect - just out of curiosity I tried it with source built editor and it does not break there, maybe this will help debug it somehow.
One more major critical issue that I’m experiencing right now: animations in 3 hit combo are played with a noticeable jitter at the end of the previous and beginning of the next one. All of the possible blends are set to 0. It becomes extremely noticeable when Ability Play Rate is set to 0.2 or lower - it looks like animation the current ability’s animation is blending with the next ability’s not instantaneously. The setup is done via Kubold’s kit and your tutorial.
