Lukas Tönne	f6993f72be	Fix for crash during node tree updates when a group tree is undefined. Undefined trees have no anonymous_attribute_relations, they must be ignored during the update.	2023-03-08 11:49:45 +01:00
Lukas Tönne	03d142fb5b	Added a regression test for crash during node tree update. Node tree updates can crash if the tree contains a node group that points at an "undefined" tree type. This can happen if the tree is linked from a library and the path is lost, or if a custom (python) tree is used and the script is not run.	2023-03-08 11:49:45 +01:00
