Crashed chain can't be removed - Zynthian hangs

Somehow I managed to crash zynaddsubfx. I then went to remove it and Zynthian hung on Removing Chain. Couldn’t close it in VNC-Engines - which wouldn’t help because I usually wouldn’t have that GUI available when running headless. Only recourse seems to reboot. Will file issue when time permits.
