Okay, quick Wall/Floor/Terrain question..

[Strangel]

Let's say I'm deleting useless wallpapers, floor tiles, and terrain paints..
Let's also say that there are far too many rooms in houses on two neighborhoods (complete with subhoods, Uni's, etc.) for me to check out every single possible floor, wall, and terrain choice.
For the most part, I don't even USE terrain paints. I have NO idea why I downloaded them in the first place, I just know I'm thinning the herd in all my downloads subfolders to prepare for adding Seasons.
I have Sims 2 Holiday Edition Base, Uni, Nightlife, Glamour Stuff, OFB, Pets.. I think everything but Family Fun (loading that up tonight), the little holiday pack, and Seasons. I haven't installed the Pets Patch OR the BodyShop patch but everything else is all bundled up and up to date.

If I delete a wall, a floor, or a terrain that's in use somewhere.. what's going to happen? Will I lose the ability to enter the lot? Will I end up with a default paint a la custom clothing/hair removal?

Nah.

It'll just revert to a different texture or become a blank spot of wall.

Deleting in-use terrains used to make a horribly blue blinky lots of horror, but they finally fixed that somewhere along the way. Deleting walls and floors has always been fine.
