Hi, thanks for reporting!
I don't think this is anything conflicting?
It does sound like a conflict to me. The mod only updates the speed whenever the settings are changed or a new player joins in it's current state. This means that it's possible for any other mod to change the speed afterwards while this mod is unaware of the changes.
Have you tried running a save with only Speed Settings enabled? Also, what mods do you use? And do you play solo or not?
