Did the nether get reset or something? My portals are missing

Tried to use my portal at my village, ended up in someone else's portal (turns out it was diggers? if he is the guy with the floating village thingy in a jungle biome).

Looks like my surface portals are fine, but I ended up digging down to the place where my old portal should have been, and it isn't there. I found an old nether cave that was there when I first set up my portals, but my tunnels and stuff seem to be gone/

Yeah... It got reset. 1.4 screwed with the spawning so nobody could get wither skulls.
Try to get your portals back on nethernet.
