Murderer's tracker script terminates randomly; markers disappear and never return

[AKMDM]

Script 419 controls the murderer's tracker and displays markers on the innocents. Sometimes, this script is terminated by a "division of 0", so the markers are never displayed again.

This issues seems to happen a lot on a few specific maps including WDIEX01 and WDIEX02.

This issue happen when the player load messages typefonts , or immediately print messages replacing the marks. Example wdiex03 when the player call the summon of slendy and not have enough backstabs.
note:
check the "jammed" msg of m1.
