Map was the one with 4 VP on a river in the middle of the map. Playing Melvin I think First spell thrown by Melvin was a fireball. After this, my burning fingers and ember stream (whatever its called) looked like a yellow square rather than a yellow cone. Cards worked normally, just the visuals on the tiles were wrong. Havent been able to replicate, but given its all randomised in Mp, its hard to do so.
So, when you mouse over a cone spell now it will show you ALL squares you could hit. Since you can turn around when playing the cone, this is often a very large area. Perhaps it's confusing this way.
Wait, seriously? You decided to show the "overlapping-cone-shapes-which-by-mathematical-definition-would-blob-together-into-an-undifferentiated-square" solution for communicating how the cone would work? I haven't poked at the game since the change, so I wouldn't know. But that's the one solution I wouldn't have expected you to use: an undifferentiated square really cannot communicate how the cone would work.
That's the way that all the other cards work (they show all possible targets and affected squares) so it just works this way "by default" now. I welcome other suggestions as to how it should work though!
A couple of suggestions to weigh in from a UI perspective: a) now that the cones are cancel-able, there doesn't really seem to be a need for the squarish/full preview. Just previewing the forward arc is fine, imo. The orientation overlays after activating are yellowish, so are the cone preview overlays. A trifle color clash due to too much yellow. Either one of those colors could shift. b) well, if the full preview stays...(reckon that'll be people who'll prefer it), then the overlapping squares could do with a slightly different color. You'll end up with a square and a cross right in the middle. Hope it helps.
Being able to see a firing arc when mousing over the facing arrows after clicking the spell would be pretty cool, too.
