I have a 'workaround' for this my side of things, Does DimDoors have some form of API for block placements i could hook into at all?

Sadly, no. We just use setBlockState with the flag that disables block updates for as far as I know. I'll see if I can find the code. :)

Actually, this was part of what Runemoro has rewritten, so we're not using setBlockState anymore.

https://github.com/DimensionalDevelopment/DimDoors/blob/1.12-WIP/src/main/java/org/dimdev/ddutils/schem/Schematic.java#L340-L360 Is the part i care about, sadly this is /basically/ what vanilla does for its structure system. Realistically my work around /should/ be fine, but if an api becomes available ill use that.
