Captain Obvious

While crude and inefficient programming at best, you could try putting it in the.... i forget what state it is but the one that checks every turn. making it so that every turn, the field is created in that spot, as far as i know this would not have any negative effects unless the fields grouped, and instead of 1 quickfire, you were getting hit by 200. just a suggestion.

put_field_on_space(x,y,n)

put_field_on_space(x,y,n)

i used this call (i don't remember the actual format) and used 6 for the space (quickfire) and put in the EXACT coordinates (i know i checked like 5 times) and only one showed up. there is your example.
