Teleport to /sit

I was sitting on a stairs in raveenf land claim and NIRU03 send me a tpa request. When I accept it, he fell off to ground across all blocks. He couldn't stand in floor when I'm sitting.

This can’t be fixed it’s just how the sit feature works. When you’re sitting and accept a TP request, the other player may fall through the blocks because there's no solid position to stand on. this is expected behavior and happens with any entity a player can sit in.
