Please try the latest build(s) from https://ci.viaversion.com/. In case the issue still persists send the new dump

Fixed in latest dev build on https://ci.viaversion.com/view/ViaRewind/job/ViaRewind/

i have updated and i can join now, but if i died in 1.7 i crash and cannot respawn normally, need to use newer version to respawn to play again

and with mobs not existant in old version like a frog, in 1.12 i join i see a rabbit with nametag frog, but in 1.7 i see a chicken with nametag chicken, idk if this is intended, probably not
