Out of memory loading solid

It's a complicated error that can totally up set a level designer! It appers while loading a VMF.It is rarely seen but can appear IF SOMEBODY HAS CREATED TOO MANY SOLIDS AT ONCE AND TYING THEM TO ENTITY OR WORLD. Simply just try to save your project as many times as you can and reload hammer while creating complicated solids that are combined with func_details.

Todo: write a better description

Here is an example how to erase WRONG solids: 1. Open your map file with Notepad++ and go to line that Hammer tells you where ERROR:7 exist. 2. You should find a SOLID group there. 3. While looking at it's sttings it will look like this:

solid

4. By the look there is no such location as written above "1.#QNAN". 5. Simply erase all wrong solid data from your VMF and that ought to bring your level back to usable form.
