Please report this error to the mod author.

Error while running event belt-visualizer::on_tick (ID 0)
real number expected got table.
stack traceback:
[C]: in function 'draw_line'

Thank you for the great mod !

I have no idea how this bug happened, I tried reproducing it and couldn't get anything to error. It has something to do with underground belts, specifically drawing the dash between them, but that's literally never failed before and the error is from a variable being the wrong type, which doesn't help narrow it down because there's a bunch of variables all in that specific line of code. If you have any more details about the belt, like was it actually getting destroyed? or just damaged? Otherwise I think I'm going to leave this error as is for now as some sort of freak accident.

thank you, sorry i cannot be any of assistance.
i will reenable it and see if it comes back and try to be more precise then.
