Jenne and I noticed that the SEI_DIFF node was reporting "chambers not nominal" and was stuck in its 'DOWN' state as a result. We realized this was because HAM7 ISI is tripped likely due to vent prep and impending door removal, so we removed HAMs 7 and 8 from the list of chambers that are checked in SEI_DIFF's "isi_guardstate_okay()" function. After loading the node, SEI_DIFF successfully went to 'BSC2_FULL_DIFF_CPS'.
