Describe the bug
when i log into my priest, i get an error message coming from plexus

To Reproduce
Steps to reproduce the behavior:

1. log in as a priest
2. See error

Expected behavior
i would not expect to see an error message

Desktop (please complete the following information):

• Version - Plexus-v3.1.5-cata
• Game Version - cataclysm

Additional context
here is what the error message says:
1x ...dOns/Plexus/Libs/LibHealComm-4.0-117/LibHealComm-4.0.lua:1537: table index is nil [string "@Interface/AddOns/Plexus/Libs/LibHealComm-4.0-117/LibHealComm-4.0.lua"]:1537: in function <...dOns/Plexus/Libs/LibHealComm-4.0/LibHealComm-4.0.lua:1481> [string "@Interface/AddOns/Plexus/Libs/LibHealComm-4.0-117/LibHealComm-4.0.lua"]:3454: in function OnInitialize'
[string "@Interface/AddOns/Plexus/Libs/LibHealComm-4.0-117/LibHealComm-4.0.lua"]:3594: in function ?' [string "@Interface/AddOns/Plexus/Libs/LibHealComm-4.0-117/LibHealComm-4.0.lua"]:3573: in function <...dOns/Plexus/Libs/LibHealComm-4.0/LibHealComm-4.0.lua:3569>

im not 100% sure what LibHealComm is, but i think this error might be causing issues with showing incoming heals on plexus. i dont see any green numbers when casting heals
