I consolidated all the landmines into one creature (a creature that should be more compatible with the mod's features than the mod was before I did this!) called LANDMINE. Note that there was something in the raws, don't quite remember what (except that it was a syndrome), that said [IMMUNE_CREATURE:LANDMINE:ALL]. That wouldn't work if there was no LANDMINE creature, but now there is!
This is going into the automaton mod, by the way
