Hello, great work Penguinboy and thank you for this awesome editor. I found a bug where if I try to move a light it disappears and the selection becomes very small. This happened to me in different maps created from scratch. This is in the latest version 1.0.2.4.
The bug doesn't happen if I go to Edit -> Select all -> and then move everything.
