Hey Roland,
Thanks for pointing this out — I had another look at how the Core handles the different ruin sets, and you’re right.
AbandonedRuins-base and the K2 ruin pack register their own separate sets, so there’s no real reason to block them. The Core simply uses whichever ruin set is selected, so they can coexist with combined just fine.
The main reason I was cautious here was actually Silly. It has functionality that can merge its ruins into the currently selected ruin set, which would mean those ruins could end up inside combined unintentionally and bypass the weighting/balancing I’m doing there.
So I’ll allow Base and K2 again, while keeping Silly, Fortress and RedDwarf incompatible for now.
Thanks again for making me re-check this — the Core is already designed to handle this much more cleanly than I gave it credit for.
Greetings MoSII
