Hello, Poutinator!
I'm enjoying your mod. Thank you.
I'm reporting an error while playing today.
An error occurred while pressing the hotkey to execute Quick Ride while riding the locomotive.
Thank you for making this mod!
I'm using it very comfortably :)

An error occurred while executing the quick-ride::quick-ride event (ID 38).
The LuaEntity API call failed because the LuaEntity is invalid.
Stack trace:
[C]: Inside function ' index'
_quick-ride /control.lua:140: Inside function pickup_vehicle
quick-ride /control.lua:443: Inside function <_quick-ride /control.lua:435>

I've just released 1.2.4. It adds some checks that could fix the bug, but I couldn't reproduce it on my end. If you update quick-ride, is the bug still there? If it is, can you provide me more detail? Are you playing with other mods that change vehicle behaviors or adding new locomotives?
