Info:
This plugin blocks bugged explosions known as GhostMining.
Fixed to do this in correct way.
Metamod plugin by Jussi Kivilinna has some bugs like blocking explosions right under feet. This one blocks only GM explosions.
Shootings from gauss on lamps also blocked by this plugin, because they are GhostMine explosions.
CVARs:
gm_block_on "1" // (Default: 1) Enable/disable GhostMine blocking.
ChangeLog:
v1.0 [2011.03.06]
Algorithm by Jussi Kivilinna impelmented in AMXX.
Initial release.
v1.1 [2012.02.19]
[!] Fixed: Will not block anymore correct types of explosions (for example one right under feet).
