[BUG] Freehand Wall Draw + Join Wall Points Crashes Scene

[Doopily1234]

Describe the bug Drawing a wall using Freehand Draw Wall and then using Join Wall Points to simplify walls causes a crash

To Reproduce Steps to reproduce the behavior:

1. Import scene background (mine was a 700kb jpg)
2. Use Freehand Draw Wall to create complex walls including Windows
3. Click Join Wall Points multiple times until walls stop jittering as they combine
4. Try to create a Light
5. The light fails to render, and error messages show in console. Leaving scene and returning shows a black scene

Expected behavior This should cull very short wall segments and create more efficient walls, but it seems to not be properly deleting and instead creating many zero-length walls
