Thanks, I just did that and no more error codes. Oddly, game + the mods still worked perfectly. It was 2 of them not updated in awhile, Loot Multiplier and Unrestricted Portals.

Valheim Plus has identical portal function so that was easy, but doesn't handle creature drops at all, just pickable and gatherable - and isn't fully H&H updated yet as doesn't have onion support for loot multiplication.

Loot Multiplier seems to work and use some generic multiplier function because even though not updated in some while, works fine with H&H - onions and all pick, gather, and creature drops.
