Recompiled the map and extracted the modified lmp with vbspinfo
Added vscript to respawn the decals (Thanks to Shadowsyn for pointing out this possibility)
Note: This still requires an lmp file to remove the infodecal from the bsp, unless there's a way to delete them with vscript before the map loads.

Test Update
- Rebuilt lmp headers with lmpfix

Restored 5 infodecal (The arrows that point to saferooms)
