When ship started to fly, i paused thrust and the this happened

The mod Orbital Transfer (0.1.2) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event orbital-transfer::on_space_platform_changed_state (ID 186)
orbital-transfer/control.lua:48: attempt to index field 'space_location' (a nil value)
stack traceback:
orbital-transfer/control.lua:48: in function 'space_platform_enter_orbit'
orbital-transfer/control.lua:447: in function <orbital-transfer/control.lua:431>

Taking a look now, I'm guessing I neglected to handle pausing mid-flight. Thanks for the report.

Fixed in 0.2.1, let me know if it still occurs!
