Yes I did encounter more errors down the line with other mods using holopatcher, in that case ignore my last message I didn't know holopatcher wasn't considered a fully working TSLPatcher replacement at the time, sorry for bothering with a non issue.
I mean it could also be a conflicting mod, I'll dig deeper and report back if I find anything (for context, I am following this guide: https://kotor.neocities.org/modding/mod_builds/k1/full)
I'll also add that I'm using holopatcher instead of tlspatcher, I'll try with tslpatcher as well.
I am experiencing an issue installing the mod with the "KOTOR Community Patch-Compatible" option on version 2.3.
I'm getting this error: [Error] Unable to modify GFF field 'InventoryRes'. Path 'ItemList\3\InventoryRes' does not exist!
From what I could find and understand, it seems that it's because CP.ini targets index 3 of a 3 items table (hence ItemList\3 not existing) instead of rebuilding the list programmatically.
I guess it should still be fine, but I'd rather report the issue since I encountered it.
