there seems to be some issue with with the DO Pillars.
minecolonies-1.18.2-1.0.765-ALPHA.jar
domum_ornamentum-1.18.2-1.0.50-ALPHA-universal.jar

When placed on top or bottom of an block the top/bottom is missing, when placed on the side of a block it is correct.
when updating the blockstate by connecting to another pillar and breaking again it fixes it.
Its not an rendering issue because it crashes the game when breaking it from an specific angle

Just found the cause of the issue on my end, seems like its some conflict with the mod Effortless Building, after deactivating the mod, the pillars seem to get placed correctly.
