The most difficult part could be that going back to like it was before (bots would only shoot a breakable if a connection went right through it, which prevented bots from shooting more than one breakable and thus could cause them to get stuck) is not a good solution. Bots should still be able to destroy two or three annoying breakables (e.g. wooden boards that block a shaft entrance), but only if a connection passes nearby... I hope that's possible.
