Tested that and, yes, it still crashes.
...I decided to nuke that install and created a fresh EasyTutu instance. Now at I can add map notes as long as I don't install that component
EDIT: I get the same crash trying to import a character... So, I decided to pick up BG:EE. Installed everything in the Tweak Anthology and it seems to be perfectly stable after 40mins of play. I wanted that old school feel just one more time, but I guess it's time to move on.
