i've written this in the comments before, not realizing there's this support thread.
Fix for 3.5.1: (at least i think. couldnt thoroughly test it)
change the call for the following function in user\mods\InsurancePlus\src\mod.js into:
inRaidHelper.isItemKeptAfterDeath(pmcData, item)
in line 157 and 167
essentially trimming the item parameter and adding pmcdata. apparently they changed the parameter list.
