There isn't an emoticon horrified enough to cope with how that made me feel!

It was already complicated enough at 2 levels.

In my current map, I do everything in just 2 levels though, because it
made things cleaner for me. Outer map specifies the offset for each
inner map, giving the location their arrow must start from (ie. what is
the offset of the piece of cave the arrow starts from). Inside that is
the offset of that piece of cave compared with the offset of the
previous piece, which creates the arrow.

Therefore there is only ever 2 levels of offset. It does mean that if
you change 1 map's offset by 1 metre, you must also update the offset
for every map down the chain. But it was still easier than infinitely
nesting maps (17 offset levels deep!).

But I just tested it done with multiple levels, and my offset arrows
still work, so I cannot reproduce the behaviour you described. It is
always the inner-most offset (so to speak) that creates the arrow. At
least with my stuff - you doubtless have much more complex stuff than me.
