I'm thinking the overall accuracy should be just fine as far as people noticing even with a ton of overlapping hogs, and this way we can tell the difference between a hog and "something else". For experiment and rope-breaking purposes, make rope pass through hogs.

8313952b2811 suggestion of mikade's - delete old mines if the collision array shows signs of filling up. This is kind of an edge case, esp now that array is up to 1024, but should prevent (easiest) way to crash by collision array overflow (endless mines/minestrikes).

c509bbc779e7 Revert prior attempted optimisation. Gridding the land pays in some situations, but not all. Restricting to an upper bound might help, but overall, seems too fuzzy to be worth it. On one side is increased cost of Add/Delete + extra test on collision check, on the other is skipping the list iteration. Perhaps for large lists.
