game crashes if nodebox is nil

[berengma]

makes a server unplayable because game crashes repeatedly when a mob meets a node with nodebox = nil.

easy solution line 180:
if node.drawtype == 'nodebox' then
if node.node_box == nil then return nil end -- <- This is new and to be added
if node.node_box.type == 'fixed' then

First I need to investigate why such a node exists, then maybe I'll be able to determine the height instead of making it impassable by returning nil.

Would be grateful if you'd be kind to temporarily add this to your local fix and report the result:

if node.node_box == nil then
minetest.chat_send_all('nodeboxless: '.. node.name)
return nil
end

good idea.

i tried to find it with grep yesterday, but failed in using the right parameters and sorting output

it is farming_redo on Lilly:

Thanks, master updated, please check if it solved the problem.

mobkit updated on server, until now it is save, even with players and mobs near melons

Case closed then, thanks!
