Mouse not working on grounded

I also have this issue, though I've had this happen on ground too. Scroll zoom also ceases to work, but keyboard, mouse, and stick controls continue to function.

I think a common ground rule when playing is, if a game doesn't have integrated keyboard and mouse support... then using a keyboard and mouse adapter in order to get around that is technically cheating. The peripheral isn't official authorized by Microsoft
like the mod said, so it wouldn't be a good idea to go ahead and use it or keep using it because that's unfair to the other players if the game doesn't have full keyboard and mouse support and everyone else is on controllers. You know what I'm trying to say?

make adjacent rows of 10 ground, 10 ground w/seed, 10 missing ground w/water, 10 ground w/seed, 10 ground w/torches, 10 ground, 10 missing ground (put water here...doesn't work, 10 adjacent ground.

Surface is good, because in the Warframe(another game with mouse nad keyboard support) mouse works well and in the main menu Fortnite mouse works well too, this problem is in the match only.

I start up fortnite then plug in my keyboard and mouse and only my keyboard works how do i fix this ?

What model of keyboard and mouse are you using?. There is of course a work in progress for both, I highly suggest using a wired Keyboard and mouse only at this current moment on fortnite.

Both are wired but mouse wont work on any game is my mouse broke???
