GML Visual: Instance position does not update despite valid direction/speed

[gm-bug-reporter]

Description

Originally developed against an older GML Visual based tutorial. GMLv used initially but the bug appears regardless of if GML is used or not.
The Debugger appears to show that direction, speed and hspeed at all set correctly at runtime.
Additionally, I recreated this project with the same exact GMLv and the issue does not appear there.
I compared the Object and event yy files and they're identical.

Also to verify that the event fires I put in a show_debug_message and it fires so it seems related specifically to speed/direction.

Steps To Reproduce

1. Start the game in Debug mode
2. Press left
3. Observe that none of the instances move left
4. Pause in debugger and check the speed, direction, and hspeed variables
5. Observe that they all are the expected values.

This is not a bug with GameMaker itself, but one in your project, so I will close this issue now. For coding support, please visit the GameMaker Community forum and create a thread there, asking for advice.
