I think that programs without bugs unfortunately are illusions.
Mods are very near to program (in our case mods are described by metadata instead that code but it is the same).
In mine opinion,
bugs should be resolved as soon as possible
taking into account the context,
here we have a open source game
therefore patience and tollerance are the first choices In mine experience a lot of bugs made more and more damage that what they should do.
I mean that in a lot of cases the effects of a bug could be
reduced.
As example, while we waiting Hobbes/Solarious fix them RMP node issues with all the time they needs,
if Developers share the idea,
them could study some euristic to allows Battlescape survives after these errors:
node chain could be cut on first error
or node outside map boundary could be move to legit boundary place.
Errors avoided (bettere reduced) should be logged to allows a future real and complete solution.
In this case RMP error effect move from program crash
to few aliens do not patrol on the map
