Another question i have come up with after reading the new icons rules. When a hovering character moves it ignores the effects of hindering terrain, it fails to mention that they dont have to stop when they enter an opposing characters adjacent square. Does this mean hovering characters have to stop just like grounded figures now or did they leave this out by mistake?

im not gonna quote the rulebook, but any flying character, meaning either hovering or soaring, ignores the effects of characters on movement. hovering charatcers however still have to break away from adjacent characters.

The line about ignoring the effects of opposing characters IS absent from the new rulebook. Does this mean that hovering characters now have to stop when moving adjacent?

From the Icons Rule Book, page 17:

A flying character occupies its square regardless of flight mode. No other character can
occupy the same square as a flying character. Flying characters may move through squares adjacent to and occupied by opposing characters.
