Hi,
at first i suggest not to play permadeath with many mods, the risk that you got an unexpected mod conflict increase with the number of mods.
At my expierence ROM vampire/werewolfes don't work well together with Rim of Magic. They can work but i got some trouble in the past. Special since ROM don't get develop anymore and just updated (so far i know).
There are 2 unusual long error msg. with torranmagic (Rim of magic).
Maybe visit their Mod Discord channel:
https://discord.gg/gFYfA6rand ask there about it.
