Have loaded into several missions switching out companions with the Astral bond mod. but the mod doesn't seem to work at all if your frame is Excalibur Umbra
edit
Would also seem that it just outright doesn't work as a client
Further testing
it seems whenever switching to a sentinel/pet with it already installed causes it to not work. un-equiping and re-equiping the mod seems to fix it
testing cont.
seems even re-equiping doesn't work consistantly
Final Edit (I hope)
The problem seems to be, whenever you enter Operator/Drifter mode from the Orbiter/Hub Zones Astral bond becomes Inactive until you go back into the mod config and Re-equip it.
Final Final Edit...
After a few missions where I haven't touched my Operator key until i get in mission... the un-equip,Re-equip method still Isn't consistant... Kindof at a loss here.
Actual Final Final Edit
When it does function. if the pet or sentinel dies mid mission the mod become inactive once again
