Skill gem missing?

I'm not sure the cause of this bug, but it seems that my primary skill gem managed to despawn, along with the socketed support gems. I fought my way with fireball from the jungle into the temple of chaos to do my 2nd ascendancy trials, but then upon entering the trial noticed that fireball no longer had a keybind. After looking around it seems like it pretty much completely vanished. Not in my stash, not on the ground in any of the previous areas, and I hadn't talked to any vendors recently enough to somehow accidentally move it from the skills page, to my inventory, then vendor it before entering the trials. I was wondering if anybody else has had a similar issue? If so, any resolution? Unfortunately out of support gems due to a minor re-spec and lost my main source of dps, so further progression seems unlikely. When I try to craft another copy of the gem with another uncarved skill gem it says that I can't because I already have the skill equipped. Very very odd.

I remembered my support gems for infernal hound disappeared when I respecced out of the hound ascendancy points, they never got back into my inventory or stash.
