Short description:

when a network becomes corrupted by going in and out of safemode, the reader crashes the server if its reading the corrupted network

Steps to reproduce the problem:

1. put a reader against a network to read it, can be the reader's own network
2. (might be optional) expose the recipe/active crafting jobs aspect of the reader onto a card, and display this card
3. (might be optional) pass this card into an operator that does some calculation and put it in a display panel or a tunnel component
4. an example i did in my world:

recipe_in :: Recipe -> Ingredients
Ingr.items :: Ingredients -> [Item]
get_or :: [a] -> Int -> a -> a
item_empty :: Item (an empty item card)
applyTo_2 = pipe flip apply
pipe^2 = expOpRes_2 (pipe_2 pipe pipe)
expOpRes_2 = flipPipe apply2
pipe_2(0) = flip (pipe flipPipe flipPipe)
pipe_2 = expOpRes (pipe_2(0) pipe_2(0) expOpRes)
flipPipe = flip pipe

get_orEmptyi = applyTo_2 get_or item_empty :: [Item] -> Int -> Item
Recipe_Item = pipe^2 recipe_in ingr.items get_orEmptyi :: Recipe -> Int -> Item

now make 25 Int cards Int_n :: Int (n = 0 -24) starting from 0 to 24, and do

active_job_list :: [Recipe]
recipe_empty :: Recipe (empty recipe)
firstRecipe = get_or active_job_list 0 recipe_empty 
nItem = apply2 Recipe_Item firstRecipe Int_n :: Item

now put nItem (n = 0 -24) into 25 different exporters
5. restart the server in safe mode
6. restart the server in normal mode, now all networks should be in the state "corrupted network" (not sure if this is intended as it is extremely tedious to update all your networks everytime after going back from safe mode)
7. updating any corrupted network should make the network work again, so we update the network that has the network reader before we update the network the reader is reading
8. crash

Expected behaviour:

server shouldn't crash in step8
