hnnnnng doom builder removing textures that can't be seen but will be later

what exactly causes this, editing adjacent sectors or something? what if I "bury" these linedefs in more sectors, could it save them from losing textures? if someone could look in the code, I would be very grateful!

Creating new sectors, it seems. I just pasted a texture where it can't be seen, and then used Make Sector tool; the texture was removed, even though nothing really changed.

Not to mention SURPRISE STARTAN on untextured walls. 8-P

Yeah, it seems that DB removes textures when you need them (like in this case) and adds textures when you don't need them (untextured holes for monsters, different light levels, etc). :)
