Great mod, thanks alot =) I fixed this myself by a rollback but just for the record;

Character corpse expired while in /editor

Where Is MyBody (1.1.3) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event WhereIsMyBody::on_tick (ID 0)
Given entity doesn't exist anymore.
stack traceback:
[C]: in function 'draw_line'
WhereIsMyBody/control.lua:86: in function 'redraw_lines'
WhereIsMyBody/control.lua:97: in function <WhereIsMyBody/control.lua:94>

Thanks, it looks like that other mod has removed this entity in the same tick. Or the player has no body or corpse.

bump
