>:O I don't have the money for so many ponies!

Hm. It seems to be related to rendering on my dedicated GPU; when I switch to the internal card (Intel HD 4000), portal 2 builds the map just fine.

Also for some reason I got banned from thinkingwithportals.com.

Keep it coming I'm so eager for this.
Also where's the time when I used to be good at coding

My record is still something like 2:30 minutes I'm too lazy to learn the sophisticated algorithms

my birthdate is 22-01-1998
so i'm 16 now (unless my parents lie )

That's something I once thought about... What if everyone lies and everything you think you know about yourself is a lie?

We're talking preinstalled linux here. That is, OEM software.

The TiLP in the repos is really outdated. You should compile it from source, it isn't too hard. You can grab the install script here. Before running this script, run this:
sudo apt-get install git autoconf automake libtool libglib2.0-dev zlib1g-dev libusb-dev libgtk2.0-dev libglade2-dev libsdl1.2-dev gettext bison flex groff texinfo xdg-utils libarchive-dev intltoolCopy-paste that into the terminal, hit enter, enter password, give permission to install them things. That should get you the latest version of TiLP.

I've heard (from a dev) that folders were never really looked into because the devs thought nobody really used nested folders
