How can someone else reproduce it?
User configurations:
- Launch a craft with a separator with part tagged "sep".
- Hostname
import krpc
conn = krpc.connect("Test", "10.0.0.51")
sc = conn.space_center
ves = sc.active_vessel
sep = ves.parts.with_tag("sep")[0]
sep.decoupler.decouple()What is your environment?
- KSP 1.12.3
- Mods: KRPC 0.5.3, KOS, LaserDist
- Python: 3.11.2
Anything else we need to know?
I don't really use separators myself, so this bug does not affect me personally. I just discovered this issue while testing and wanted to let you know.
