Bug of Range Check Aura

[tawdry meadow]

Bug: mouseover range check condition will sometimes not function, if any target is selected.
Example Aura: https://wago.io/wqAQyREmI
Expected behavior: the Aura should turn red when the mouseover non-friendly unit is out of 30 yards, regardless of having a target or not.
Bugged behavior: the Aura will sometimes not turn red in the case above, if any target is selected. It may resume to the expected behavior after some further try.
Gameplay footage (the top left icon in my WA area): https://streamable.com/72sh95

P.S. I might have encounted such issue since 9.2.7, during which I started preparing WA for 10.0, decided to add some range check conditions, did not figure out a constant result, and finally gave up. I'm currently doing an iteration of WAs and trying range check again, and just recorded the gameplay footage above that seems to show an obviously inconsistent result, which I believe to be either a bug from WA or limited/wrong information provided by Blizzard.

The Range Check trigger is actually the only built in WA Trigger that can properly handle the mouseover unit. Your Unit Characteristics trigger will often be inaccurate.

It seems that the problem happens if you're mousing over a friendly unit and move directly to a non-friendly unit. Trigger3 doesn't update frequently enough to pickup that mousover has updated information.

either remove that trigger or make it a custom trigger that checks more often

Thank you for the explanation. I'll have a raid night soon, but my goal is to get this custom trigger done this week.

Can you shed light on where I should start from? I assume it relates to 1. unit characteristic custom trigger. and 2. checks the info on every frame.

Does it affect FPS a lot?

anything that checks everyframe will take more resources yea

wether thats enough to affect your fps idk you'll have to test it

the other option is don't check if they are friendly

All I'd like to achieve is to duplicate what action bars show. I disabled all addons and was surprised that even the default action bar handle this "out of range color" things perfectly: spells like Taunt turn red only when a mouseover hostile unit is out of range, spells like Gorefiend's Grasp the mass grip will turn red on a friendly unit as well; whatever default spell icons or @mouseover macros, they all handle the out of range color perfectly out of the box.

the default bar is checking everyframe probably
