BG1 areas are missing when installing to EET with bp-bgt-worldmap

[ahungry]

When running the game with a combo of TDD-1.14 + TDDz-1.3.1 (side note: to get it installed required "rsync -a ./TDDz/_CORE/ ./TDD/" first, as it was missing a scrx41.itm in the tdd/itm folder initially) or @RoxanneSHS fork tagged at TDDz-1.5, I notice the mod is causing all BG1 areas to disappear from the worldmap (BG2 areas and custom areas I can't reach show - but missing BG1 areas prevents me from leaving Candlekeep/Lion's way and getting anywhere in a full EET playthrough).

If I uninstall TDDz, and try with many other large mods (RoT, DSOTSC, NTSOTSC etc.) the map still performs as usual.

Could this be an issue with bp-bgt-worldmap thinking I'm on a pure BG2EE instead of EET? Or something TDDz incorrectly changes in my copy?

I'm on GNU/Linux if that matters.
