Create-an-Arena: Multiple Props Have Larger 'Invalid Location' Zones

Several props (ex: Wall designs) appear to have larger than normal ‘Invalid Location’ areas
making them more difficult to place.

Example Wall props:
4 – RAW 2006
5 – RAW 2002
38 – Stage Curtain
40 – Flag
43 - RAW 2020

Workaround: None
