While working on a modpack I was testing world creation and found an issue with Blueprint and Biologica, the crash report listed Blueprint, so I thought I'd report it here first before bringing it to the Biologica team.

At first I thought it was an issue with Sinytra, but that turned out not to be the case.

Debug:
debug-1.log

Feature order cycle issue - never has anything to do with Blueprint, since it doesn't add any worldgen features. Feature order cycle is when biomes add features incorrectly/out of order. Cyanide / Feature Recycler can help identify / fix this but it looks to be caused by Biologica.
