If the underlying issue of effect potential vs. negation effects is the problem, then patching over an over-situational card with an errata when the card is pretty irrelevant in the metagame anyway is a bad idea.
The real hiccup comes from situational negation, which shows up in UFS more than I think any other CCG around today. Naruto & Dragonball have a lot of situational negation too, but those generally don't interact with the effects of an ability, rather they use the keywords on the Ninja/Warrior using the Jutsu/Technique (and in DB's case, the keywords on the technique itself).
That's not something that can be "fixed" with an errata - it'd need a fundamental re-working of the way we play abilities... or alternatively, a complete C&D on all future "situational negation" like Killer Android, Red Lotus, et al. - because if it's not negating the entire ability, it can instead respond at the trigger event, akin to Spiritual Center. Make an effect intended to work like Killer Android instead do "R Commit: When one of your assets would be destroyed, that asset is not destroyed. Destroy 1 asset." There, functional ability that does not cancel the entire effect, but merely shields your asset (assuming there's another asset out to destroy instead of the one you're protecting... etc).
