The crash was caused by a change in the MineTest api. A function that previously returned the information "this node does not exist" (which is important information for a mod that works in very diffrent environments - not all nodes have to to exist in each game) was changed so that it now deliberately crashes the game when a node doesn't exist (motivation: "controlled environment - when a node doesn't exist, it was a typo and is a severe bug").
There is no way to protect any mod from such unexpected api changes.
Anyway - reworking the mod also lead to better wool cover nodes which now take up far less node definitions and offer more colors. And general bugfixing/adjustments.
Curious but makes game(server) fail at start
