TFS 0.3.6 SPAM (luaGetThingFromPos) Tile not found

[dantexd]

Basicly this spell what it does is push the target, but when pushing into nowhere my console gets spammed with this (luaGetThingFromPos) Tile not found and my game freezes, how could I make a restrinction if tile not found then move to nearest tile?

Thanks 4 reading and Regards!
