Thanks for the advices! Yeah I already checked my whole LO with SSEEdit several times because I had to edit a lot of my esps and flags in order for the game to even start up. But Summermyst really might be the issue I have that installed. But I don't see any suspicious behaviour in my papyrus log, I will look again. Never knew of the Philosophers Stone entchantment I thought I only get the effect when activating that standing stone, but I am not really familiar with that part of Skyrim I haven't really played the game so far, only modded it and now want to start and play it lol
I also have Ordinator, I have seen it has a similar trait but I have comb.-patches for all my entchantment/perk overhauls.
Do you know wich line it is in the script you looked at? :3
Oh and to the investment/banking, yes I have Evolving Value Economy (SkyRem Economy) at Skyrim Special Edition Nexus - Mods and Community (nexusmods.com)
