Not exactly sure if this is a real bug or not, but traps (In my case, the trap was set via flag) seem to go right through any and all "No Enemy" flags. They also go right through solid combos.
Edit: I have confirmed that this is not a bug. It was a mistake on my part.
What other traps quest rules/screen flags do you have on? The floating traps screen flag may be causing some of this behavior. If it's checked, try disabling that or other quest rules first and see if this is still happening.
I bet "Multidirectional Traps" isn't checked in your quest rules.
If this rule isn't checked, traps will have NES-compatible "move through everything" behavior.
Ah, that might be the problem, DarkDragon. I'll try that, thanks. 😊
Edit: Yup, it works fine now. Not a bug
