Right! So, so sorry for the delay! My work lately has been... work intensive. But, a bit of a break for a while! I took a look at the log you uploaded (thank you for that), and it's unfortunately not my bug: RLA Stockalike has tripped me on this a couple times, where a typo was made. [ModuleManager] Applying node /zROMini/@PART[*]:HAS[@DRAG_CUBE]:FOR[zROMini] to RLA_Stockalike/Parts/Structural/struct_various/small_decoupler_stack/RLA_small_decoupler_stack [ModuleManager] Error - Failed
