My Crystal Isles Map and Rag map are crashing. We have never had this issue before.  I am curious does it have something to do with the release of Gen2?   Its telling me I have exceeding 12GB   which I have never done until the release of Gen2

ARK, in general, is using more RAM than what was considered base line since the latest update. It's not too much more, about 300 MB at idle and about 10MB per player afterwards on The Island, and about 400 and 20MB respectively on a few modded maps I have. Crystal Isles is already well known for Memery leaks and crashes, and RAG for overspawns.  

If your servers were cresting at just below 12GB (by around 1GB or less) then this latest update t the game probably pushed them over.
