Floating lines (above heads) not cleared between maps

[cambragol]

I may remember this being the case in original Fallout 2, however, it is certainly happening with Fallout 2 CE.

I tested in Fallout 2 and in Fallout Sonora, and in both games floating lines above NPCs heads are not cleared when moving between map screens.

Often this is not noticeable, as there are not so many NPCs near an exit grid. However in certain locations it is very noticeable. An example would be the Shark Club in New Reno. Enter the casino, wait for lines to appear over NPCs heads, then go upstairs. The lines will appear upstairs too.

Is this a bug? Does not seem like ideal behavior.
