- Deluge/Violent Gale/Volcano tiles will now fail to be placed on cells that are already ocuppied by anything else.

- status_is_immune will now return 0 or the amount of immunity of the target. In which cases it returns 100 for WoH and the GTB bonus when they have passed the gtb_sc_immunity setting. This enables targetted spells to not "fail silently" unless GTB's magic reduction is 100.
