Hey there Ninja Monkey! I am sorry you are having issues, I've been unable to reproduce these issues, i have tested on all 3 modes with map exploration mode off, so there must be something more to it! Would be happy to get to the bottom of this asap, thank you for reporting it :)
But 4 more things, you are not running both the Basic and Advanced version at the same time right?
And have you tried deleting the plugin from the active plugins list and re adding it??
And are you using the latest version of RPG Maker MV as in, 1.6 from steam?
Last, if you've already tried those 2 and theres been no change, I'll need you to reproduce that crash error "r of null" and press F8, then take a picture of the top most error / Red Text, in the console, that'll better allow me to track it down!
