In 26.1 Pre 1 the placement of configured features blocklist moved to placed features and with it some bugs sneaked in such as fire not generating on netherrack, but any other block in the nether
as well as soul fire only generating on soul_sand, and no longer soul_soil anymore
this is is caused by the addition of
”type”: “minecraft:not“, before listing the matching blocks for where fire_patch and soul_fire_patch should generate
In the attachments are screenshots of places/blocks fire now generates as well as a comparison of the same seed where fire generates in 1.21.11 and 26.1 pre2 as well as the code responsible for this bug in placed_feature/soul_fire_patch
