Villager guards sometimes do not use their offhand totems upon recieving fatal damage.
Provided screenshot context:
The aftermath of a quarrel between Guards and Vindicators in this screenshot.
Villager guards are equipped with armor, swords, and a totem. The totem should be used instead of dropped.

Please try using the mod alone and recreate this scenario, if this doesn't happen with the mod alone it could be due to a mod conflict.
