The Save locations and Move route core plugin bug?

The last couple of days i have been trying to figure what was wrong with my events and i have finally narrowed it down.
The entirety of my this can be found here as well the links to the plugins themselves.
As you can see i couldn't make heads or tails of the situation and began to suspect the strangest of things.

To keep it short save locations on a map seems to be causing the teleport command from the move route core plugin to be ignored in some cases but not all.
I will show you how i tested it with some illustrations.
To demonstrate it i had made a small project but the file is to big to be uploaded and i don't know which files you will need/ have changed, so for now i hope the pictures are enough.
(changed the common event, variable and switch limit added 3 plugins the 2 mentioned before and Yanfly core plugin.
Created 3 maps copied a common event and some events in the maps.)

Is this a bug? Is it supposed to work like this and i'm simply using it wrong? Can someone tell me?

Greetings Jetboost.

What save locations? What move route core? You haven't even identified the plugins/authors, much less provided links to them. We can't tell if there's a bug if we don't know what plugins you're using. We can't tell if you're using them correctly. Maybe there's an incompatibility (which technically is not the same as a bug) but we can't tell.

As i had mentioned but i will put them here as well with the prerequisite Yanfly core engine the moveroute core and the last one save event locations.
Author: the plugins are all from Yanfly.

Thanks for the fast reply btw.
