movement_factor in materials.xml does not seem to do anything anymore

[zootal]

Linux dedicated server. I modified materials.xml, adding/increase movement_factor for various materials. I've done this since A14 or so, and it's always worked. In the current version, Alpha 19.2 (b4), I have this for various materials:

 

<property name="movement_factor" value="1.750" />

 

And it does nothing. Movement speed remains unchanged.  Does this no longer work, or is movement_factor hard coded somewhere such whatever we put in materials.xml gets ignored? Again - I've been doing this for years. It stopped working with A19.

Well let's just make this even weirder. I went to join server and got this: ERR Loading player data failed for player '76561197960378421', rolling back:

 

And my player profile on the server got wiped. And now the movement factor is recognized. This is too weird. Does movement_factor get read and stored with the player profile upon initial creation, and ignore subsequent changes?

Sounds like an issue in the edits. More data would be needed though.  I've also used the movement modifier for years to hinder or improve movement based on terrain, but haven't written it for a19.
