Tested on a dedicated MP server with 12 clients JIP-ing in and out over two hours. Mod was loaded as server Mod only. Craters were awesome, worked great, and AI on the Headless Clients did not (seem to) have issues patching. Server FPS (90) took minor hits (82) during heavy shelling, but not much more than usual. Primary (client) FPS drop seemed to come from the decal spawning, actually. Decals were cleaned up / "disappeared" after a short delay, this may be engine behavior.

Feature Requests:
- (raised) crater and crater debris objects exist in Arma. determine the center of the terrain deformation and spawn these raised craters/debris around the sides?
- temporary particle vfx to make the crater smoke. on maps with tall grass it's extremely difficult to find the craters without this. can be toggleable
- ensure deformation data is stored in a table so that you can optimize the heightmap data in the JIP queue, see the second example in the biwiki page for setTerrainHeight. not doing this means it can't really be used in long-duration, high-playercount ops
- disable the deformation feature entirely on terrains with huge terrain cell sizes (Malden)
